Autofocusing Electronic Autocollimator – E
This new instrument is a precise USB3.0 device combining the functionality of an autocollimator with motorized feature for accurately focusing at finite distances. It is extremely accurate with a resolution down to 0.01 seconds, with a clear aperture of 36 mm. Special version allows measurements of laser propagation as well as alignment telescope and centering device.
Featuring:
1. Illumination – built-in illumination can be switched between R, G & B, wherein the R will yield higher level of illumination (several times higher), and a combination of the three could also be selected.
2. The system will be offered in two operating modes:
- Beam Analysis – alignment of laser beams to Autocollimator optical axis and analysis of laser incoming directions and divergence angles.
- Autofocusing Autocollimator – new features such as Virtual Image denoted from -2.5 meters to -, coupled to focusing on Real Images from 17.5 cm to infinity. Added lateral displacement measurements on images you’re focused on.
3. Fast Mode Image Processing and Recording – Up to 1,000 times per second.
