Narrow band filter is a major role in light of a specific wavelength through, let the other wavelengths of the light reflection ( or attenuation)of optical components. Half wave width is usually controlled in 20nm or smaller, ultraviolet, visible light, near infrared wavelength, far infrared wave band . My company's narrow bandpass filter using multilayer epidural by ion assisted deposition of nanometer materialsand high vacuum evaporation coating, good compactness, high imaging definition.
Plated with hard, long service life,
Ion plating, low temperature drift
High penetration rate,
High cut-off depth

Optical Surfaces Requirements: The lens application drives the requirements for surface irregularity and surface quality.
Used where wavefront distortion is not as important as cost
Excellent for most general laser and imaging applications
where low wavefront performance must be balanced with cost
For laser and imaging applications requiring low wavefront distortion,
especially in systems with multiple elements
Used for low power laser and imaging applications
where scattered light is not as critical as cost
Excellent for laser and imaging systems with focused beams
that can tolerate little scattered light
For demanding laser and imaging systems
where minimizing scattered light is critical
Wedge Lens (ETD, mm)
<0.25mm x 45°or upon requirement
