SHPF-25C-650 25 mm Dia. Mounted Shortpass Filter; t=3.5mm 650nm

The SHPF-25C-650 is a 25 mm diameter Shortpass Filter, offered by OptoSigma, a renowned vendor in the optical industry. This filter is designed with a thickness of 3.5mm, making it a robust and durable choice for various applications.

The filter's primary function is to allow light to pass through while blocking wavelengths above a certain value, in this case, 650nm. This is particularly useful in applications where the detection of shorter wavelengths is crucial. The cut-off point is set at 650nm, ensuring that only light with wavelengths less than this value can pass through.

The filter is coated with OptoSigma's proprietary coating, both on the front and back surfaces, enhancing its performance and durability. This coating is specifically designed for shortpass filters, ensuring optimal light transmission and blocking efficiency.

The SHPF-25C-650 is shaped like a thin lens, which is beneficial in applications where a flat surface is not feasible or desirable. This shape allows for easier integration into optical systems and ensures that the filter does not introduce significant aberrations.
