62-977 12.5 mm Dia. Hard Coated High Performance OD 4.0 Longpass Filter; t=2 mm 550nm

The 62-977 is a high-performance longpass filter, boasting a 12.5 mm diameter and a thickness of 2 mm. This filter, sourced from Edmund Optics, is designed to transmit light with wavelengths above 550 nm, making it ideal for applications that require the blocking of shorter wavelengths.

The filter is constructed with a base shape of a circle, ensuring uniform transmission across the entire surface. It features a hard coating on both the front and back surfaces, enhancing its durability and resistance to wear and tear. This coating also aids in reducing surface reflections, thereby improving the overall transmission efficiency.

The material ID of the filter is UVFS Mal-1965, indicating its specific composition and manufacturing process. The physical data of the filter reveals that it is cut on 550 nm, meaning that the transition from high to low transmission occurs at this wavelength. The cut off is 0, indicating that all wavelengths below 550 nm are blocked.

The filter is designed in the shape of a thin lens, suggesting its potential use in optical systems where a thin, lightweight element is required. The catalog number for this filter is 62-977, and it is currently in stock, as indicated by its weblink status.
