Optical Roof Prism
Roof prism usually requires a very high roof angle accuracy(generally 90 ° + / - 5 seconds), and the roof edge is not allowed to have cracks. When we process roof prism, we have very effective protection measures to ensure that there will be no cracks at the edge of the roof. Because of the high precision requirement of the roof angle, we will use a plane laser interferometer to measure the interference fringes produced by the reflected light of two roof surfaces, and calculate the roof angle according to the interference fringes and the refractive index of the material.
