The 33-027 is a 30.5 mm diameter Deep UV Bandpass Filter, specifically designed to pass wavelengths at 248.00nm. This filter is sourced from the reputable vendor, Edmund Optics, and is available for purchase through their website. The filter is currently in stock, as indicated by its weblink status.
This optical component is classified as a Bandpass Filter, which means it allows light within a certain range of wavelengths to pass through while blocking other wavelengths. In this case, the 33-027 filter is designed to cut on at 238nm and cut off at 258nm, making it ideal for applications that require the precise transmission of deep ultraviolet light.
The filter is made from a material identified as "uvfs mal- 1965", and it has a thickness of 1.5mm. The coating on both the front and back surfaces of the filter is "edm 33-023", which is likely a proprietary coating developed by Edmund Optics to enhance the filter's performance.
The 33-027 filter is shaped as a Thin Lens, suggesting that it may have some light-bending properties. However, without more specific information, it's difficult to say exactly how this shape will affect the filter's performance.
