834FDC25 25 mm Dia. Bandpass Dichroic Filter 850nm

The 834FDC25 is a high-quality Dichroic Filter, sourced from Knight Optical, boasting a 25 mm diameter and a thickness of 0.7 mm. This filter is designed to transmit light within a specific range of wavelengths, making it an essential component in various optical systems.

The 834FDC25 is a Bandpass Dichroic Filter, which means it allows light to pass through a specific range of wavelengths while blocking light from other wavelengths. The cut-on wavelength for this filter is 808nm, and the cut-off wavelength is 890nm, making it ideal for applications that require the precise filtering of light in the 850nm range.

This filter is made from N-BK7 Schott, a high-quality optical glass known for its excellent optical properties and durability. The filter is coated with a special coating, referred to as 'kni 834fdc-0', on both the front and back surfaces to enhance its performance and durability.

The 834FDC25 is designed in the shape of a Thin Lens, which is a type of lens with a very small focal length compared to its diameter. This design allows the filter to be used in a wide range of optical systems, from microscopy to telescopy, and everything in between.
