Introduction to optical mirrors
In today’s application field, optical components – optical mirrors, optical mirrors have excellent performance in terms of reflectivity and durability. As a manufacturer of professional optical components, MOK Optics’ optical mirrors are of course also quality-controlled, especially in the band of 450 to 12000 nanometers. This article will detail the characteristics, technical parameters and importance of MOK Optics’ protective silver-coated mirrors in various applications.
1. Overview of Protective Silver-Coated Mirrors
1.1 Advantages of Silver Coating
Silver is a metal with extremely high reflectivity, especially in the visible and near-infrared bands. Although unprotected silver-coated mirrors excel in reflective performance, they are susceptible to oxidation and scratches due to their soft surface. Therefore, in order to extend their service life, MOK Optics uses a protective dielectric coating to ensure the stability and durability of the silver-coated mirrors in various environments.
1.2 Function of protective coating
The main functions of protective coating include:
– Prevent oxidation: Silver is easily oxidized in the air to form silver oxide, which affects its optical properties. The dielectric coating effectively isolates the air from the silver layer, thereby preventing oxidation.
– Increase wear resistance: The dielectric coating has a higher hardness than the silver coating, which can effectively prevent scratches and ensure that the surface of the mirror remains smooth.
– Enhance reflective performance: By optimizing the design of the coating, the dielectric coating can not only protect the silver coating, but also enhance the reflectivity in a specific band.
2. Technical parameters of optical mirrors
2.1 Reflectivity
MOK Optics’ protective silver coated mirrors have an average reflectivity of more than 95% in the wavelength range of 450 to 12000 nanometers. This high reflectivity makes it widely used in laser systems, spectrometers and other optical equipment.
2.2 Size range
– Size range: 3mm to 200mm
– Size tolerance: ±0.02mm
– Net aperture: greater than 90%
MOK Optics’ mirrors can be customized according to customer needs and adapted to different optical systems.
2.3 Surface quality and flatness
– Surface quality: up to 10-5 level
– Flatness: λ/10@632.8nm
High-quality surface treatment ensures uniform reflection of light on the mirror surface and reduces optical distortion.
2.4 Parallelism of optical mirrors
– Parallelism: up to 30 seconds
This parameter ensures precise docking of the mirror in the optical system and reduces errors in the optical path.
3. Types of coatings for optical mirrors
