Product features:
Equipped with standard microscope objective lens base and pinhole base;
The micro objective lens base is adjusted with a micrometer head, which can continuously and quantitatively adjust the distance between the objective lens and the pinhole;
The guide rail adopts precision linear ball guide rail pair, which has comfortable movement and high precision;
The pinhole seat consists of two m6x025 fine tooth screws to accurately adjust the pinhole position in two dimensions.
Product functions:
The main purpose of this product is to restore the laser beam that affects the energy distribution due to the defects of the passing optical devices and the scattering of particles in the air during the transmission process through the combination of micro objective lens and pinhole. This is very important for optical experiments and related research, especially in the field of holography and optical data processing. When used, the spatial filter is placed in the optical path, so that the laser beam is injected into the microscopic objective lens, and the spatial filter is adjusted to make the beam reflected from the microscopic objective coincide completely with the incident light beam. Then, the position of the pinhole and the distance between the objective lens and the pinhole are adjusted, so that the beam is accurately focused on the pinhole, that is, the adjustment is completed.
