Optical glass color filter in normal use process should pay attention to small details

Substrate materials for optical glass optical filter in use process should pay attention to the usual small details: 1. In the usual in use process should be carefully take put as much as possible, at the same time pay attention to the external environment, avoid clothes zippers, buttons, such as scratches to the filter, or put the filter in the environment of the dirty or dust. 2. Filter for a little while to bring finger contact, avoid salt and acid corrosion of substrate surface. 3. Take take filter for a little while to hand edge filter, even with a finger, and don't contact filter of pervious to light. 4. Color filter should be placed on a clean, soft objects, not on the glass, metal, table, or do not clean paper. 5. Storage capacitor should be placed in a clean when wrapped in paper or special lens cleaning paper. Storage temperature is best at about 23 ℃, humidity is not higher than 40%. In dry storage compartment is better. The main purpose of the optical filter is formed in the cavity light reflex, to form a stimulated. In some of the laser, fold in the cavity mirror, placed in laser beam incident Angle of 45 degrees position can make the polarized light beam. In both cases, is very critical to the user, choose a reflective lenses in order to ensure that the laser energy in the most appropriate level, and achieve the desired polarization. However, they have the same weakness, such as compared to other metals, they are more flexible. The chemical activity of the silver will lead to the formation of surface compound, such as sulphate and chloride. These compounds will lead to reflect lens performance degradation, leading to fall off from the basement membrane layer of silver. In high power CO2 laser, generally used horizontal laser cavity design, use of transit in the active laser medium multiple reflection beams. Tail mirror combination by a 45 degree Angle of incidence of folding mirror, and a normal incident Angle of reflective lenses, often can revolve around the incident optical axis.
