OptoSigma's VPF-50S-10-45-40000 is a 50 x 50 mm optical glass bandpass interference filter with a central wavelength of 400nm. This filter is designed to transmit light within a specific range of wavelengths while blocking other wavelengths, making it ideal for applications requiring narrow-band light transmission.
The filter is rectangular in shape, with dimensions of 50mm x 50mm, and has a thickness of 3mm. It is cut on at 395nm and cut off at 405nm, ensuring a tight control over the transmission band. The coating on both the front and back surfaces is Opt VPF-10-45-40000, which is specifically designed for this type of filter.
The VPF-50S-10-45-40000 is shaped as a thin lens, which can be beneficial in certain optical systems. The catalog number for this filter is VPF-50S-10-45-40000, and it can be found on the OptoSigma website, where it is currently in stock.
