730FDS50 50 x 50 mm Shortpass Dichroic Filter 730nm
The 730FDS50 is a high-quality dichroic filter, measuring 50 x 50 mm, designed for shortpass applications with a cutoff wavelength of 730nm. This filter is sourced from Knight Optical, a renowned vendor known for their extensive catalog of optical elements.
The filter is made from N-BK7 Schott, a popular optical glass due to its excellent homogeneity, low auto-fluorescence, and high damage threshold. The rectangular shape of the filter, combined with its thin lens geometry, makes it a versatile component for various optical systems.
The coating on both the front and back of the filter is KNI 730FDS-0, which is specifically designed for shortpass applications at 730nm. This coating ensures high transmission at wavelengths below the cutoff while effectively blocking wavelengths above it.
The physical data of the filter includes a cut-on wavelength of 0nm and a cutoff wavelength of 730nm. The filter has a thickness of 1.1mm, which contributes to its robustness and durability.
The 730FDS50 is currently in stock and available for immediate purchase on the Knight Optical website. The provided weblink leads directly to the product page, ensuring a seamless shopping experience for users.
