535BP40 10 mm x 10 mm Surface Coating; Bandpass Filter Surface Coating

The 535BP40 is a Bandpass Filter, a type of optical filter that allows only a specific range of wavelengths to pass through it while blocking others. This particular filter, sourced from the reputable vendor Omega Optical, has a catalog number of 535BP40 and is available for purchase on their official website.

The filter is rectangular in shape, with a width and height of 10 mm each, and a thickness of 3 mm. It is made from a material identified as "uvfs mal- 1965", which is not specified further in the provided data.

The 535BP40 has a central wavelength (CWL) of 535 nm, which is the wavelength at which the filter's transmission is maximum. The filter's cut-on wavelength is 515 nm, and the cut-off wavelength is 555 nm. This means that the filter begins to transmit light at 515 nm and stops transmitting at 555 nm, effectively passing only the light in the 515-555 nm range.

The filter features a surface coating on both the front and back sides. This coating, identified as "ome 535bp40", is likely a proprietary coating developed by Omega Optical for this specific filter. The coating plays a crucial role in the filter's performance, ensuring the specified wavelength range is transmitted while other wavelengths are blocked.

The 535BP40 is shaped as a Thin Lens, suggesting it may have some focusing or magnifying properties, although this is not explicitly stated in the provided data.
