VPF-50S-12-65-89000 50 x 50 mm Optical Glass Interference Bandpass Filter 890nm
OptoSigma's VPF-50S-12-65-89000 is a high-quality optical glass bandpass interference filter, designed with a rectangular base shape and a size of 50 x 50 mm. This filter is specifically centered at 890nm, with a 12nm bandwidth, making it ideal for applications that require narrow-band filtering in the near-infrared region.
The filter is constructed with a thickness of 3mm and features a UVFS Mal-1965 material ID. It has a cut-on wavelength of 884nm and a cut-off wavelength of 896nm, ensuring precise filtering capabilities. The cut-on and cut-off wavelengths, along with the central wavelength (CWL), are crucial specifications for selecting the appropriate filter for your specific application.
The VPF-50S-12-65-89000 is coated with OptoSigma's proprietary VPF-12-65-89000 coating on both the front and back surfaces. This coating enhances the filter's performance and durability, providing reliable and consistent results.
The filter's shape is classified as a thin lens, which is a type of optical component with a thickness that is small relative to its other dimensions. This shape is often used in optical systems to minimize optical aberrations and improve image quality.
