69-219 25.2 x 35.6 mm Dichroic Shortpass Filter; t=1.05mm 750nm

The 69-219 is a Dichroic Shortpass Filter, measuring 25.2 x 35.6 mm, with a thickness of 1.05mm, sourced from the renowned optical vendor, Edmund Optics. This filter is designed to selectively pass light of a certain wavelength while reflecting or absorbing other wavelengths, making it an essential component in various optical systems.

The filter's primary function is to allow the transmission of light below 750nm, while blocking or reflecting light above this wavelength. This is particularly useful in applications where the detection of specific wavelengths is crucial, such as in fluorescence microscopy, spectroscopy, and other optical detection systems.

The 69-219 features a rectangular base shape, typical of many optical components, allowing for easy integration into various optical systems. The filter is made from UVFS Mal-1965, a material known for its optical properties and durability.

The coating on both the front and back surfaces of the filter is EDM 69-183, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance, ensuring efficient light transmission and reflection across the specified wavelength range.

The filter's geometry, with a width of 25.2mm and a height of 35.6mm, is designed to fit standard optical mounts and systems. The thickness of 1.05mm ensures the filter's structural integrity while minimizing optical distortions.

According to the vendor's website, the filter is currently in stock, indicating its availability for immediate use or purchase. The filter's catalog number, 69-219, can be used for easy reference and ordering.
