The case this came with is... fine. It needs to be a bit bigger, and with the expectation that buyers might want to put a little more in it than it came with. The charger is hard to get back in and there is no space for extra batteries if you do. Still, cool to have a case included.

UV bandpass filters typically cover the UV spectrum from about 200 nm to 400 nm. Here are some common ranges in this UV spectrum:

I was hesitant to purchase something less than practical for so much money, but I enjoy it every time I use it! This thing feels exactly what you expect a lightsaber to be! And turn that thing on, and anything within 10 feet away from you is in danger of being charred! (Focused just right, I got it to light a firecracker almost 12 feet away!) I don't use it all the time, so I only need to recharge it every few months. For improvement, I would like to see a better charger. Mine always has th red light on, and never turns green, even after sitting for 16 hours. I have to time my charges so I don't ruin anything. The laser has nothing to be complained about! I can even burn things underwater!!!! Remember that for lasers this powerful to NEVER have it on for more than 30 seconds. You don't want the focusing and emitting crystals to start deteriorating on you! Thanks Zeus Lasers!

A UV bandpass filter is a filter that transmits UV rays and blocks other wavelengths. These optical filters are widely used in scientific, industrial and medical applications. The transmittance of UV bandpass filters is generally 15-30%. Due to material reasons, most UV bandpass filters cannot be highly transparent.

If you don’t know how to choose and judge, you can contact our optolong professionals, who will give you detailed answers based on your needs.

A dual-band UV filter is a specialized filter capable of transmitting two different wavelength ranges, typically one in the UV and one in the visible or infrared spectrum. These filters can be used in multispectral imaging systems that need to capture images in ultraviolet and other wavelength bands simultaneously.

These filters are characterized by their ability to provide a clear cutoff between the UV wavelengths transmitted and the visible light blocked. This steep transition is often applied in forensic analysis where all visible light must be eliminated to see only UV-induced fluorescence, or in systems where high optical performance and low light loss are required.

In the medical field, ultraviolet light is one of the most effective ways to kill viruses and bacteria. Meanwhile, in clinical diagnosis, UV filters help diagnostic equipment accurately observe the fluorescent response of microorganisms and other biomarkers in body fluid samples.

Each type of UV bandpass filter serves a unique purpose and is optimized for different performance characteristics (such as bandwidth, transmission efficiency, and blocking capabilities) to effectively fit a variety of UV applications.

Yes, UV bandpass filters can be customized to meet the specific requirements of an application. This includes adjustments to diameter, thickness, substrate material and spectral properties.

I have had my green zeus laser for a couple years now and it is still amazing. I have it setup with the 5x beam expander and it is so dam good. Wish i wouldve waited and gotten the more powerful 2watt one they have now or whatever but this one is still amazing. i made sure i didnt leave it on for over 30 seconds at a time and it seems to be the same brightness still :) 10/10 Worth it.

So, since purchasing the 7watt Zeus x, I have been having a lot of fun. Everywhere in my apartment there are burn marks ! Different objects create dazzling effects. Anything glass is especially fun. Outside, once you attach the expander and get the focus just right, you can ignite stuff over 100feet away. The batteries must be fresh and the laser must be perfectly still at those distances. Also got the rgb laser. One thing I especially like is when in white mode, the star caps separate the three colors to really cool effect! So, I just ordered the new dual diode 15 watt blue laser. I’ll let you know how it goes ! Thanks Zeus, I’m having a lot of fun. Though my wife hates these things !!

Unlike narrowband filters, broadband UV filters allow a wider range of UV wavelengths to pass. These filters are used in applications that require a broader spectral response, such as solar UV research or environmental monitoring where multiple UV wavelengths are required to detect or measure various substances.

My biggest worry here is that the spring connecting the batteries to the laser unit extends outside of the housing. This means that unless you are careful, the spring can catch the foam in the case and bend it... which will eventually break it off. This laser is almost the length of my forearm when assembled. Another 1/4 inch to cover that vital part would be fine. Or if not possible, a smaller connecting spring.

But the core function of a UV bandpass filter is the ability to isolate specific UV wavelengths, which is useful in a variety of applications, from forensic analysis to sterilization processes.

Already own a couple of the 7 watt zeus x lasers , and these are like a lightsabre ! love them. So when I saw that there was a 15 watt on sale , I had to look twice ! ,then look twice again... Tried to convince myself that I did not really need this , failed miserably ,lol. This laser is an absolute beast , burns anything instantly , and great for long distance engraving ! So glad I failed to convince myself. LOVE THIS ! LASER HEAVEN ! Thank you zeus , great to do business with you again , so good I bought 2 ! ... now looking at the green 2 watt...LOL

In scientific research, UV filters are essential for observing substances that exhibit specific reactions under UV light. For example, in biological research, by using UV filters to observe the fluorescence response of biological samples, scientists can identify and track specific molecules and proteins within cells.

UV band filters are widely used in imaging technology and are particularly suitable for capturing the reflection or emission properties of UV light. UV filters in general photography are mainly used to block ultraviolet light below 400nm while allowing visible light between 400-700nm to pass through.

The only company that sent my laser pointer in complete kit, with batteries and everything. I really appreciate it. Thank you!

UV bandpass filters selectively transmit ultraviolet (UV) light while blocking other wavelengths of light. These filters enable precise control of UV radiation in a variety of applications. UV bandpass filters come in many types, each with its own unique materials and construction methods.

I've collected somewhat of an arsenal of Zeus Lasers& accessories including the pro and the X. But every so often I check the website just to see if anything new has come out, and when I saw this I wrestled with it for a while, thinking 'what can 15 watts do that 7 can't? Then it hit me: a whole bunch of ideas starting off with... Igniting things from 20 feet away. So maybe I talked myself into it, but after it arrived only 4 days later and I was able to fulfill all my curiosity with wonder, I felt lucky that I had found out about these when I did.

There are many types of UV bandpass filters, each designed to meet the specific requirements of different applications. Here is a detailed description of some common types of UV bandpass filters:

In summary, after understanding some basic information about UV bandpass filters, I believe you will have certain insights and judgments. Before making a choice for your application, you should be well prepared with a budget buying guide, which will help you make a decision faster.

Let’s read this article to explore the definition of UV bandpass filters and the unique advantages of its various types in order to choose the most suitable filter for a specific purpose.

I purchased two (2) Zeus X 7 Watts Blue Laser over a year ago from this website (Zeus Lasers) giving them 5 Star Ratings for their products overall excellent performance and durability. Now, I purchased and tested the Zeus XTR 15 Watts Blue Laser and its truly having two (2) times the power in all aspect of the device listed speicifications. Beware some other Laser websites listing the same 15 watts blue laser and showing the same products images with price ranging from $400 to $699, but maybe just an imitation or copied device or unverified.

Fokussiert nicht richtig zum Punkt. Ist wohl eher ein kleiner Strich wie schonmal von jemanden erwähnt. Trotzdem sehr stark und man kann so einiges damit an Spaß haben. Vorallem bei Nacht.

The power is there. Easily ignites material from 20 feet. The beam/dot was a bit thicker than I was expecting, but impressive to see in the day and just absurd at night. USE THE EYE PROTECTION. Or you'll have blue/purple spots in your vision for a half hour... or worse.

I did not buy the Zeus Pro 2 directly from Zeus Lasers, so I have no acquaintance with their company other than their product.

For specific applications, custom UV bandpass filters can be designed and manufactured to meet unique requirements. For example, Optolong Optics, their website not only provides a variety of optical filters, but also provides users with a variety of customized filters services to help users solve incompatibility issues.

UV bandpass filters are typically made from materials such as fused silica or borosilicate glass, which are chosen for their ability to withstand high-energy UV radiation and environmental durability.

In industry, UV filters are widely used in quality control processes. For example, in semiconductor manufacturing, UV filters are used to detect tiny flaws and contaminants on chip surfaces. In addition, these filters are used to check for unevenness and defects in coatings and plastic products to ensure product quality.

Narrowband UV filters transmit primarily a very narrow range of UV wavelengths while blocking other visible and infrared light. These filters are highly selective and ideal for scientific and medical applications where precise wavelength isolation is critical, such as fluorescence microscopy or analytical instruments that measure specific UV-absorbing compounds.

In forensic science, the use of UV filters can reveal traces of blood, body fluids, and steganography that are invisible under normal lighting.

A note on shipping - I ordered this on a Friday night... so it didn't really get moving until Monday. It took less than 3 days after that. 5 days total, but once it shipped, it moved at crazy fast speed.

Astronomers use specific types of UV filters to study objects that primarily emit UV wavelengths, such as Optolong’s Venus-U filter, which can be used to observe Venus.
