OptoSigma's VPF-50S-12-60-66000 is a 50 x 50 mm optical glass bandpass interference filter centered at 660nm with a 12nm bandwidth. This filter is designed for applications that require narrowband transmission and high blocking of unwanted wavelengths.
The filter is made of high-quality optical glass with a rectangular shape, ensuring a large clear aperture for optimal light transmission. It has a thickness of 3mm, providing robustness and durability. The filter's coating, "opt vpf-12-60-66000", is applied on both the front and back surfaces, enhancing its performance and longevity.
The VPF-50S-12-60-66000 features a cut-on wavelength of 654nm and a cut-off wavelength of 666nm, with a central wavelength (CWL) of 660nm. This specificity in wavelength transmission and blocking makes it ideal for various applications, such as fluorescence microscopy, spectroscopy, and other precision optical systems.
The filter's thin lens shape further contributes to its performance, minimizing optical aberrations and ensuring high-quality imaging. It is currently in stock and available for purchase through the OptoSigma website, as indicated by its valid weblink status.
