The difference between short wave infrared, near infrared, medium wave infrared and long wave infraredNear Infrared (NIR): Wavelength between 0.75-1.4 microns, defined by the absorption of water, usually used in optical fiber communication due to the low attenuation rate in silica glass. Wavelengths Read More

F-number is commonly used for LWIR lens selection, yet lenses with identical nominal F-number can exhibit distinct field performance. The differences stem from optical transmittance, coating quality, athermal design, aberration control, cold reflection suppression and manufacturing consistency. F-number is a necessary but insufficient metric. System integrators should conduct full-temperature and scene-based field tests instead of relying only on datasheet F-number. Read More

From July 25-28, 2023, Rising Optics participated in IDEF'23 in Turkey, showcasing our latest infrared optical technologies and solutions. Our booth was located in Hall 11, 11A-40-2 and attracted a large number of visitors. We demonstrated the strength of Rising Optics with our professional and inno Read More

About Infrared LensThe infrared lens uses a special optical glass material, and uses the latest optical design method to eliminate the focal plane shift of visible light and infrared light, so the light from visible light to infrared light can be imaged on the same focal plane, so that the images ar Read More
