Light transmission depends on the filter used. In the case of colorless diffusion films, the theoretical transmission is approx. 92%; in the case of the milky opal panes, transmission can be graded down to approx. 30%. We usually sample different materials on request, which our customers can then test.

365nm UV flashlights are renowned for their precision and the clarity of the fluorescence they induce. When exposed to a 365nm UV light, fluorescent objects glow brightly, revealing intricate details that might not otherwise be apparent. What sets this wavelength apart is its near-pure UV output. You will see far more detail and a greater range of colours in gemstones than any other wavelength. This is why 365nm is especially prized among gemologists, mineralogists, and serious hobbyists.

A diffusing lens or diffuser is used to break up and distribute light evenly. Light rays incident in parallel are distributed in different directions and thus produce diffuse, glare-free light. Diffuse reflection and refraction of light are the optical effects used for this purpose. They are achieved by a rough surface and / or embedded colour pigments or diffuser particles. One classic area of application is the use of diffuser films in the backlight unit (BLU) of LCD displays. Newer fields of application are

On the one hand, there are colorless diffusion films that break up the incident light in different directions by means of a rough, structured surface, thus leading to a diffusion and better distribution of the light. On the other hand, we offer diffusion filters, which are milky opaque in color and at the same time contain diffuser particles in the material, through which the light is diffusely distributed over the surface. A combination of both variants is also possible, i.e. an opal diffuser with a structured surface.

We have suitable films and sheetss for light diffusion for direct, vertical light as well as for lateral edge lighting. Please contact us!

For instance, 395nm UV flashlights are excellent for illuminating “black light” reactive items. Think of a fun bowling night under UV lights, where everything from your neon shoelaces to glow-in-the-dark bowling pins light up spectacularly. Pest control professionals also use these flashlights as certain pests, like scorpions, are known to glow under 395nm light.

TTV mainly offers diffusing screens and light diffusers made of cast acrylic (PMMA) in different thicknesses and varying levels of transmittance but we also offer other substrates such as POLYCARBONATE.Since there is no one suitable material for any given application, we always sample several materials from which the customer can choose the best one ensuring that most of your application requirements can be met.

This lack of interference light allows 365nm UV flashlights to activate even faint traces in fluorescent objects, making them ideal for close-up work and precise detection. For instance, forensic scientists often use these flashlights to reveal hidden fingerprints at crime scenes, and art restorers use them to detect alterations or repairs in paintings and antiques.

Ever found yourself wondering “What exactly is the difference between a 365nm vs 395nm UV Light Torch? Thankfully, you probably never have!

You were relieved to find a website with only a handful of different models, thinking it would make the decision on which one to buy easier. But still, you found yourself thinking, “do I buy the The Pro: Ultra-Violet 10w 365nm UV Torch?” or “is the The Illuminator 395nm Ultra-Violet Torch / UV flashlight the better choice for my needs?”

We offer light diffusers and filters cut and machined according to customer specifications.For thicknesses up to 2.0 mm, the maximum size is approx. 500 x 400 mm for opaque and approx. 800 x 800 mm for colorless, matte materials. For thicknesses greater than 2.0 mm, formats larger than 1000 x 1000 mm are also possible in individual cases.

In summary, the choice between a 365nm and a 395nm UV flashlight comes down to your specific needs and application. For close-up work, faint detection, and detailed investigations, the 365nm UV flashlight is unrivaled in its ability to reveal fine details. On the contrary, for broader illumination of UV-reactive objects and larger surface inspections, the 395nm UV flashlight shines.

For broader illumination the The Illuminator 395nm Ultra-Violet Torch / UV flashlight will light up your world. Ideal for illuminating “black light” reactive items or detecting pests, it’s an invaluable tool for both fun and serious investigations.

Importantly, a 365nm flashlight produces less unwanted “interference light”, often seen as a visible purple light in the longer 395nm wavelength. This might lead some to believe that the 365nm flashlight is weaker because it appears less bright or more white. However, this is a common misconception. In reality, the ‘whiter’ light is indicative of a higher concentration of UV energy and less visible light. Thus, the more visible UV light you see, the less effective it might be for detailed, faint detection work.

On the other hand, the 395nm UV flashlight emits a longer wavelength, which results in a more visibly purple light. While this may result in less detail being revealed in fluorescent objects, it does provide a broader, more visible beam of UV light. This makes it particularly useful for applications where widespread visibility is more important than fine detail.

Both in conjunction with conventional light sources and with LEDs. They can prevent or at least significantly reduce unpleasant HotSpots with point or linear light sources.

Another widespread use of 395nm UV flashlights is in the hospitality industry, particularly in hotel cleanliness inspections. The visibly purple UV light is effective in revealing unclean surfaces and stains that are otherwise invisible to the naked eye.

Whether diffusers actually provide homogeneous illumination depends on the type of diffusing filter used, the light source used and the distance between the diffuser and the light source. We will be happy to send you various material samples for testing on your specific application and installation situation.

Remember, the visible brightness of a UV flashlight can be misleading and should not be the primary determinant of its effectiveness. A quality UV flashlight is an investment that can reveal a hidden world of detail, whether it’s a precious gemstone, a critical piece of forensic evidence, or a scorpion lurking in the dark.

It was at this point you finally found yourself wondering that strange question you never thought you’d ask: “What exactly is the difference between a 365nm vs 395nm UV Light Torch?

Whether you are a forensic scientist examining the scene of a crime or an enthusiastic gem collector looking to identify a valuable stone, understanding the intricacies of ultraviolet (UV) flashlights is essential when it comes to choosing the right UV Torch. But what exactly is the difference between a 365nm vs 395nm. What makes the 365nm a more or less useful UV flashlight compared to its 395nm counterpart, and how does this affect their respective applications?

Before delving into the specifics, let’s first consider what the ‘nm’ in 365nm and 395nm stands for. It refers to ‘nanometres’, a unit of length that measures the wavelength, or ‘colour’, of light, including light that isn’t visible to the naked eye. In the case of UV light, shorter wavelengths generally correspond to a higher energy level, which influences how materials react when exposed to them.
