10CGA-850 25.4 mm Dia. High Performance Colored Glass Alternative Longpass Filter 850nm

The 10CGA-850 is a high-performance colored glass alternative longpass filter, designed with a diameter of 25.4 mm and a thickness of 1.1 mm. This filter, offered by MKS/Newport, is a part of their extensive catalog, available for purchase directly from their website. The catalog number for this item is 10CGA-850, and it can be found under the "Filter" category, specifically under the "Color Glass" subtype.

The filter is designed to cut on at 850nm, allowing light of this wavelength and longer to pass through, while blocking light of shorter wavelengths. The cut-off wavelength is 0nm, meaning it will allow all wavelengths longer than 850nm to pass through. This makes it ideal for applications where longpass filtering is required.

The 10CGA-850 features a thin lens shape, with coatings on both the front and back sides. These coatings, identified as "new 20cga-850", are designed to enhance the filter's performance and durability. The filter's geometry, including its diameter and thickness, are designed to provide a balance between optical performance and physical robustness.
