The narrow band filter optical lenses
The so-called narrow-band filter is subdivided from the band-pass filter, and its definition is the same as that of the band-pass filter, that is, the filter allows the optical signal to pass through in a specific wavelength band, and deviates from the band-pass filter. The optical signals on both sides are blocked, and the passband of the narrowband filter is relatively narrow, generally less than 5% of the central wavelength value.
The main function of the narrow-band filter is to pass light of a specific wavelength and reflect (or attenuate) optical components of light of other wavelengths. The half-wave width is usually controlled at 20nm or less, and can be used in ultraviolet, visible light, near-infrared wavelengths, and far-infrared bands. Our company’s narrow-band filters are formed by high-vacuum evaporation of multi-layer hard films and ion-assisted deposition of nanomaterials. Good compactness and high imaging definition.

UV Fused Silica Standard Precision Right Angle Prisms
Right angle prisms are typically used to bend the image path or turn the light path by 90°.
Combining two right angle prisms can also combine the image and deflect the beam.
