66-060 50.8 x 50.8 mm Hoya L-37 Longpass Color Glass Filter 370nm

The 66-060 50.8 x 50.8 mm Hoya L-37 Longpass Color Glass Filter is a high-quality optical component designed for use in a variety of applications. Sourced from the renowned optical vendor Edmund Optics, this filter boasts a robust set of features and specifications that make it a reliable choice for users in need of a 370nm longpass filter.

The filter is a Color Glass type, which means it is made from a specially formulated glass that selectively filters specific wavelengths of light. In this case, the filter is designed to allow light with wavelengths of 370nm and above to pass through, while blocking lighter wavelengths. This makes it ideal for use in applications where it is necessary to isolate and study specific wavelengths of light.

The filter has a rectangular shape, with a width and height of 50.8mm each. It has a thickness of 2.5mm, making it a relatively thin and lightweight option. The filter is cut on 370nm, meaning that it begins to allow light of this wavelength and above to pass through at this point. It has no specified cut off point, indicating that it allows all wavelengths of light above 370nm to pass through.

The filter is coated on both the front and back with EDM 66-038, a proprietary coating developed by Edmund Optics. This coating is designed to enhance the filter's performance and durability, ensuring that it maintains its optical properties even under demanding conditions.

The filter's shape is that of a Thin Lens, which means that it is designed to focus light onto a specific point. This can be useful in a variety of applications, including imaging and spectroscopy.
