1. Introduction of WIDE ANGLE COLLIMATOR?
The Wide Angle Collimator is a precision optical instrument designed for testing and calibration of optical devices having reticles. The instrument projects a wide-field infinity image that enables accurate inspection of reticle dimensions, centering, orientation, and alignment with respect to the optical axis. It also provides a convenient reference for evaluating reticle offset and optical alignment during assembly, calibration, and maintenance procedures.
2. Typical Applications ?
The Wide Angle Collimator is suitable for a wide range of optical testing tasks, including:
- Measurement angle dimension of reticle
- Measurement elevation and azimuth range of reticle
- Measurement field of view of optical devices.
