Optical Flat Plate Application Scenarios

Optical flat plate is an optical element with high-precision flatness and parallelism.

It is usually made of optical glass or other optical materials, and the surface is finely ground and polished to achieve extremely low surface roughness and extremely high flatness.

The main uses of optical flat plates include:

1. As a reference surface for optical measurement: used to detect geometric parameters such as flatness and parallelism of other optical elements.

2. Constructing optical systems: In some optical devices, it provides stable and flat support and guidance for the optical path.

3. Interference measurement: In interference experiments, it is used as a reference plane to generate interference fringes for precise measurement.

When choosing an optical flat plate, the key parameters to consider include:

1. Material: Different materials have different optical properties and physical properties, such as refractive index, thermal expansion coefficient, etc.

2. Size: Choose the appropriate size according to specific application requirements.

3. Flatness and parallelism accuracy: This directly affects its performance in the optical system and the accuracy of measurement.

When using an optical flatbed, be careful to avoid collisions and scratches on its surface, and keep it clean to prevent dust and stains from affecting the optical performance.
