NHOTM-50.8S3.3 50.8 x 50.8 mm N-BK7 Ultra-violet Cut Filter; t=3.3mm
OptoSigma's NHOTM-50.8S3.3 is a 50.8 x 50.8 mm N-BK7 Ultra-violet Cut Filter with a thickness of 3.3mm. This filter is designed to block ultra-violet light while allowing visible light to pass through.
The filter is made of N-BK7, a high-quality borosilicate glass known for its excellent optical properties, including low autofluorescence, high transmittance, and excellent homogeneity. This material is often used in high-precision optical systems due to its superior performance.
The filter features a bandpass coating on both the front and back surfaces, identified as 'opt nhotm'. This coating is designed to enhance the filter's performance by blocking unwanted wavelengths and allowing desired wavelengths to pass through. In this case, the filter is designed to block ultra-violet light, typically below 400nm, while allowing visible light, typically between 400-700nm, to pass through.
The filter has a rectangular shape, which is a common shape for optical filters due to its ease of use in various optical systems. The filter's thickness of 3.3mm is also noteworthy, as it provides additional stability and durability to the filter.
According to the provided data, this filter is in stock and available for purchase. For more information, please refer to the vendor's website provided in the item data.
