PerkinElmer Ferroperm Optics A UV Filter centers at 620 nm (CWL 620 nm) with a maximum transmittance Tmax of 52.7% and a half-bandwidth HBW of 9 nm. This narrow-band UV filter defines a spectral window around 620 nm for precise transmission in optical instruments. Suitable for spectroscopy and imaging applications that require a defined wavelength band around 620 nm with a known spectral response.
