Notch Filters ZET642NF

Notch Filters — Model ZET642NF

ØØ25 mm.

Product Description

• Outer diameter 25.0 mm, with mechanical retaining ring
• Center wavelength: 532 nm-808 nm
• Stop band optical density: OD5, OD6

LBTEK offers CHROMA Notch Filters with a diameter of 25 mm and housing, currently available in ten center wavelengths: 457 nm, 473 nm, 532 nm, 561 nm, 635 nm, 642 nm, 647 nm, 685 nm, 785 nm, and 808 nm. The notch filters allow transmission of most wavelengths while reflecting or absorbing light in the band near the center wavelength, i.e., the stop band. Additionally, LBTEK's CHROMA notch filters achieve over 90% transmittance within the working wavelength range, with stopband optical densities reaching OD5 or OD6.

• Substrate: UVFS
• Stopband Optical Density: OD5, OD6
• Passband Transmittance: >90%

LBTEK offers CHROMA Notch Filters with a diameter of 25 mm and housing, available in ten center wavelengths: 457 nm, 473 nm, 532 nm, 561 nm, 635 nm, 642 nm, 647 nm, 685 nm, 785 nm, and 808 nm. Like other dielectric filters, notch filters will have their center wavelength shifted when used at a deviation from the design angle. Therefore, it is recommended that they be used at the design angle.
