High-light even facula adjustable projector

Abstract

The invention is a high-brightness uniform light adjustable light spot projecting device used for the optical coating monitoring system, and its main characteristics are: the light source firing box has the tungsten lamp with spotlight cover, one side of the box connecting with a fixed speed motor modulator through the supporting pillar, the outer light source of the modulator correspondingly connecting with the tungsten cylinder, and the cylinder has a focusing lens component which can move and adjust along the axis. Using this projector, it can not only produce high-brightness strong light source, but have stable modulation optical output, will achieve the desired uniform light effect. And light spot size is adjustable, so it can guarantee uniform and consistent light spot projecting, but also obtain the uniform small spot in long distance, and the light spot intensity is strong.

Description

technical field

[0001] The invention belongs to the technical field of optical coating, in particular to a high-brightness, uniform and adjustable spot light projection device for an optical coating monitoring system. Background technique

[0002] In the known technology, the light projecting device used in optical coating monitoring generally includes three parts: light source emission, modulated light wave and concentrated light transmission. The defects are: 1. The light source emission part usually uses incandescent bulbs, It is to place a flat or curved reflector behind the incandescent bulb to enhance the brightness of the emitted light. Since the light emitted by the incandescent lamp itself is relatively weak, and the light emitted by the light source in the direction of the exit aperture is scattered light or parallel light generated by reflection, and the light beam transmitted through the exit aperture is very small, most of the light is projected into the light s...
