CLDM-25.4C3.3 25.4 mm Dia. N-BK7 Cold Mirror; t=3.3mm 400-700nm

The CLDM-25.4C3.3 is a high-quality cold mirror filter, boasting a 25.4 mm diameter and a thickness of 3.3 mm. This filter is meticulously crafted from N-BK7 Schott, a renowned optical glass known for its excellent homogeneity and low thermal expansion coefficient.

The cold mirror coating on both the front and back surfaces is designed to reflect infrared light while transmitting visible light, making it ideal for applications such as beam combining, thermal imaging, and other scenarios where infrared light needs to be separated or blocked. The coating's spectral range is optimized for 400-700 nm, ensuring efficient performance in the visible light spectrum.

This filter is categorized as a thin lens due to its minimal thickness relative to its diameter. This design not only reduces weight but also minimizes optical aberrations, contributing to superior image quality.

The CLDM-25.4C3.3 is currently in stock and available for purchase on the OptoSigma website. With its robust design, high-quality materials, and precise coating, this cold mirror filter is an excellent choice for a wide range of optical applications.
