Jingsheng advantage
Jingsheng is very experienced in coating sub-regional films on the surface of the substrate. The transition area is straight and the width does not exceed 0.5mm.
2. Jingsheng has advantages in the coating of dielectric reflective coatings with broadband and large incident angles.
The thicker the coating, the better our strength can be shown.
3. Jingsheng can provide high-damage-threshold dielectric high-reflection (The photo below shows the laser destroying the film)
In order to achieve a high damage threshold, we will take the following improvements
a. Coat quickly after polishing to ensure that the substrate is "fresh", or remove the oxide layer on the surface during polishing for a period
of time before coating
b. The higher the vacuum in the coating chamber, the better
c. The higher the surface finish of the substrate, the better
