Optical Coating Test

Optical coating is a key part of optical components, which integrates optics, electronics, materials and coatings. Optical films prepared by optical coatings have been widely used in the field of optics, including consumer electronics, materials science, medical diagnosis, biological sciences, energy and other fields. The thickness and uniformity of the optical coating determine the optical performance of the film, which needs high technical requirements and high technical standards. Precise optical coating design and production means that the optical system performance and life of the components have a high standard, so as to achieve the purpose of reducing loss and costs.

The advantages of optical coating test

• Using advanced high-precision equipment, with high resolution (0.01nm or 0.01%), suitable for rapid and stable measurement of most optical films

• Support parameter measurement of multiple types of optical films

• Easy to operate, get measurement results efficiently and quickly

• Broad spectrum measurement, ultraviolet (185nm) to mid-wave infrared (5200nm) band to achieve variable angle and polarization measurement

The necessity of optical coating test

• Standard optical film: If the thickness is not uniform, there will be the disadvantage of unstable optical performance, resulting in low quality of its optical components, and its life span will be greatly reduced.

• Customized optical film: To meet the customer's requirements for the optical performance of optical components (birefringence characteristics, Bragg characteristics and refractive index), it is usually necessary to adopt special technologies to achieve functional customized synthesis. Considering the appearance and performance, it is expected that the optical film has a highly uniform thickness. Therefore, the thickness of the optical film needs to be accurately tested.
