Ret633-5X C 25 mm Dia. Bandpass Filter by Chroma

The Ret633-5X C 25 mm Dia. Bandpass Filter is a high-quality optical component manufactured by Chroma, a leading vendor in the field of advanced optical elements. This filter is specifically designed for applications that require narrowband transmission at a central wavelength of 633 nm.

The filter is circular in shape with a diameter of 25 mm and a thickness of 1 mm, making it suitable for a wide range of optical systems. The base shape of the filter is a thin lens, which ensures minimal optical aberrations and distortions. The filter is made from UVFS MAL-1965 material, which is known for its excellent optical properties and durability.

The Ret633-5X C 25 mm Dia. Bandpass Filter features a cut-on wavelength of 630.5 nm and a cut-off wavelength of 635.5 nm, providing a narrow bandwidth transmission of 633 nm. This precise wavelength selection is crucial in many applications, such as fluorescence microscopy, spectroscopy, and laser technology.

The filter is coated with Chroma's proprietary RET633-5X coating on both the front and back surfaces. This coating enhances the filter's performance by reducing reflections and increasing transmission, thereby improving the signal-to-noise ratio in the optical system.
