Color glass filters are fabricated to selectively transmit a particular range of wavelengths or colors of light. In designing color filters to transmit a particular range, they’re also designed to block other wavelengths or colors. Sydor Optics can fabricate custom color filters to allow long wavelengths to pass (longpass), or short wavelengths (shortpass), or both (bandpass).

Notch filters can be fabricated to the most demanding specifications for use in laser-based fluorescence, multi-photon microscopy, and Raman spectroscopy, and other high-speed imaging applications. As with other types of optical filters, Sydor Optics can fabricate custom notch filters to meet your specific needs and applications.

While certain kinds of optical filters are used to narrow wavelength ranges, broadband filters are designed to do the opposite: provide exceptional transmission throughout a broad range of wavelengths (but still exclude or reject the rest). Sydor Optics can fabricate custom broadband filters in various shapes and sizes to meet your specific needs and applications.

As with other kinds of optical filters, edge filters are designed to separate a broad spectrum of light into light that is transmitted, and light that is rejected, or blocked. Edge filters can be used to reduce harmonics and light scatter and can be fabricated to function as longpass, shortpass, or bandpass filters.

Based upon customer demand, Sydor Optics offers Optical Filters made from the following substrate materials. Of course, if you don’t see a material you need, please contact a Sales Engineer, who will gladly discuss additional options that may be available.

Ultraviolet (UV) filters are used to block ultraviolet light (UV blocking), but allow visible light to pass. Sydor Optics can fabricate custom UV filters to meet your specific needs and applications including combining UV filters with other (bandpass/longpass) optical filters.

Infrared lenses are specialized optical components designed to operate in the infrared spectrum, a range of electromagnetic radiation beyond the visible light spectrum. They are used to capture and focus infrared radiation, allowing for the detection of temperature variations and thermal emissions. Infrared lenses are manufactured from materials such as germanium, zinc selenide, and chalcogenide glasses that are transparent to infrared radiation, making them ideal for this purpose.

There are perhaps about as many types of glass filters as there are applications for them. Yet despite all the variety, one thing is clear: Sydor Optics offers exceptional manufacturing capabilities when it comes to custom optical filters. With the largest collection of double-sided grinding and polishing machines in North America, Sydor Optics can precisely fabricate custom filters to meet your exact requirements, from basic prototyping to high-volume production and every step in between. While color glass filters can be ordered directly from the original manufacturer, standard surface flatness and transmitted wavefront tolerances may not meet your precision requirements which is why Sydor Optics double-sided polishing process stands out.

Neutral density filters can be used to reduce the intensity of light by reflecting or absorbing a percentage of light at a specific wavelength. Neutral density (ND) filters reduce light intensity by absorbing or reflecting light and provide even attenuation across the specified wavelengths.

Bandpass filters are basically designed to selectively transmit a particular spectrum range and reject the other wavelengths. Bandpass filters are commonly used in a variety of applications, including chemistry, fluorescence microscopy, high-speed optical imaging, and spectroscopy.

InGaAs sensors are commonly used alongside infrared lenses for imaging in the SWIR region, offering high quantum efficiency and sensitivity, making them suitable for low-light conditions. Infrared lenses play a pivotal role in ensuring precise focusing of SWIR light onto InGaAs detectors for clear and detailed imaging.
