Frequently Asked Questions

Q: What does a long wave pass filter do in infrared optical glass?

A: A long wave pass (LWP) optical filter is designed to transmit light above a specific wavelength — in this case approximately 760nm — while blocking shorter wavelengths in the visible spectrum. This makes it ideal for near infrared (NIR) imaging applications where you want to capture only the infrared portion of the light spectrum without interference from visible light.

Q: What is this colored optical glass filter made of?

A: This filter is made from precision colored optical glass. The black coloring is an intrinsic property of the glass composition itself, which gives it its specific spectral transmission and blocking characteristics — not a surface coating.

Q: What are common uses for a 760nm long wave pass filter?

A: Common applications include near infrared photography and videography, scientific research and spectroscopy, NIR sensor calibration, machine vision systems, and educational optics demonstrations. It is compatible with cameras, optical instruments, and custom-built imaging assemblies that work in the NIR range.

Q: Is this filter compatible with standard camera lenses and mounts?

A: This optical glass filter is intended for integration into optical assemblies or custom setups rather than direct screw-on lens use. Please verify the physical dimensions against your specific camera or instrument requirements before purchasing. It is well-suited for DIY optical builds and scientific instrument integration.
