Near-Infrared (NIR) Precision Aspheric Lenses
TECHSPEC® Near-Infrared (NIR) Precision Aspheric Lenses are designed at 780nm and are optimized to eliminate spherical aberration. Manufactured from S-LAH64 or N-BK7 substrates and polished through a computer numerical controlled (CNC) process, these aspheres achieve high precision performance across the NIR spectrum. TECHSPEC Near-Infrared (NIR) Precision Aspheric Lenses are available with low numerical aperture designs for applications that require beam shape to be maintained as well as high numerical aperture designs for light-gathering applications.
