27041 C 25 mm Dia. Red Bandpass Filter by Chroma

The 27041 C 25 mm Dia. Red Bandpass Filter is a high-quality optical component sourced from Chroma, a leading vendor in the field of advanced optical elements. This filter is specifically designed for applications that require precise wavelength selection within the red spectrum.

The filter is a Circular Bandpass Filter, a type that allows transmission of light within a specific range of wavelengths while blocking other wavelengths. The Base Shape of this filter is circular, making it suitable for a wide range of optical systems. The filter has a diameter of 25 mm and a thickness of 3.5 mm, ensuring durability and stability in its placement within an optical system.

The 27041 C filter is made from UVFS MAL-1965, a material known for its excellent optical properties. The filter's Central Wavelength (CWL) is 650 nm, indicating its primary transmission band. This makes it ideal for applications that require the use of red light.

The filter's coating is another notable feature. Both the front and back surfaces of the filter are coated with Chroma's proprietary coating, denoted as CHR 27041. This coating enhances the filter's performance by reducing reflection and increasing transmission.

The filter's geometry is that of a Thin Lens, which means it can also serve lens-like functions in an optical system. This versatility makes the 27041 C filter a valuable addition to any optical system that requires red light filtering and transmission.
