LOPF-25C-561 25 mm Dia. Mounted Longpass Filter; t=3.5mm 577.1-900nm
The LOPF-25C-561 is a 25 mm diameter Longpass Filter, supplied by OptoSigma, a renowned vendor in the optical industry. This filter is designed with a base shape of a circle and a thickness of 3.5mm, making it suitable for a wide range of optical applications.
The filter's primary function is to pass light with wavelengths longer than 561nm, while blocking light with shorter wavelengths. This is achieved through the use of a specialized coating, denoted as "opt lopf-561" on both the front and back surfaces. The cut-on wavelength, which is the point at which the filter starts to transmit light, is 561nm. The cut-off wavelength, the point at which the filter stops transmitting light, is 0nm, effectively blocking all ultraviolet and visible light.
The LOPF-25C-561 is made from UVFS Mal-1965, a material known for its optical properties. The filter's geometry, including its 25mm diameter, is designed to fit standard optical systems. The shape of the filter is that of a thin lens, further enhancing its compatibility with various optical setups.
The filter's status is currently in stock, and it is available for purchase through the vendor's website. The provided weblink leads directly to the product page for easy access and ordering.
