( Brand: Melles Griot ), ( Manufacturer Part Number: L41000-385-01 )
The L41000-385-01 is a high-quality etalon filter from Melles Griot, a renowned manufacturer known for their precision optics. This specific etalon is coated with YAG (Yttrium Aluminum Garnet) and is designed to operate at a wavelength of 1319nm.
The etalon filter is a type of interference filter that is used to select a narrow bandwidth of light. It works by creating multiple reflections within the filter material, which interfere with each other to create a series of narrow transmission bands. The L41000-385-01 is particularly useful in applications that require precise control over the wavelength of the light, such as laser spectroscopy, optical metrology, and fiber optic communications.
The etalon is made of high-quality optical glass and is coated with YAG to provide high reflectivity and low absorption. The YAG coating ensures that the filter is highly resistant to damage from laser radiation, making it ideal for use in high-power applications. The filter is also designed to have a flat and uniform surface to ensure that it provides consistent performance over its entire aperture.
The L41000-385-01 etalon filter is available in a variety of sizes and mounting options to fit a wide range of applications. It is a versatile and reliable tool for any optical laboratory or research facility that requires precise control over the wavelength of their light source. With its high quality and precision performance, the L41000-385-01 etalon filter from Melles Griot is an excellent choice for any application that requires precise wavelength selection.
Pros of buying a Melles Griot L41000-385-01 etalon:1. High-quality material: Melles Griot is known for its high-quality optical components, and this etalon is no exception. It is made of fused silica, a material widely used in optical applications due to its excellent optical properties.
