UV Pass Filter
UV Pass Filters are precision optical filters designed for ultraviolet imaging and spectral selection. They transmit UV wavelengths while blocking visible and infrared light. This makes them suitable for scientific research, inspection systems and optical detection applications. Chenyu Optics manufactures UV pass filters in optical glass and fused silica, with custom UV transmission ranges, sizes and coatings.
UV Pass Filter Overview
UV Pass Filters are precision optical filters that transmit required UV wavelengths. They block unwanted visible and infrared spectral components at the same time. This provides accurate ultraviolet transmission and spectral selection for demanding optical systems.
Using advanced optical coating technology, UV pass filters provide high transmission at target ultraviolet wavelengths. They also deliver excellent visible light blocking performance and reliable spectral separation. As a result, engineers use them in UV imaging, scientific research, inspection systems and optical detection applications.
In addition, Chenyu Optics supports custom UV pass filter manufacturing according to customer requirements. This includes custom substrate material, dimensions, wavelength range and coating design for prototype and repeat production.
