• Block Visible Wavelengths
• Ideal for Machine Vision Applications
• Can Be Used as Cold Mirrors
Designed to pass short-wave infrared (SWIR) wavelengths
while blocking visible light, TECHSPEC®
SWIR Longpass Filters are ideal for increasing the
image quality of InGaAs cameras in a variety of machine
vision applications. These longpass edge filters
are offered in multiple sizes and cut-on wavelengths.
TECHSPEC® SWIR Longpass Filters can also be used
as extended cold mirrors to eliminate damage or adverse
effects caused by heat build-up.

• Reflects Stated Color While Transmitting
Remaining Visible Spectrum
• Ideal for Color Separation Applications
• Precision N-BK7 Substrate
Our Reflective Dichroic Color Filters are designed to
be used at a 45° angle of incidence and will reflect the
stated color while transmitting the remaining visible
wavelengths. EO’s Reflective Dichroics boast higher
performance and a better quality substrate than other
readily available color processing filters. Each filter
provides greater than 98% reflection over the specified
color range and greater than 90% transmission of
the remaining wavelengths.
