GTH-4-2.2FA Operation Specifications:
Input beam: TEM00, diameter (1/e²): 4.0 mm +/- 0.15 mm;
Lens diameter: 12.0 +0.0/-0.1 mm
Thickness: 4.0 +/- 0.1 mm
Achievable top hat size: 6x diffraction limited@1064 nm, 12x diffraction limited@532 nm;
Working distance is given by focal length of additional lens which is needed always. Top Hat appears always at focal plane of additional lens.
For instance if an additional lens f=100 is used, Top Hat appears at 100 mm behind additional lens. So GTH-4-2.2FA could be easily put in front of objectives for example.
The distance between GTH-4-2.2FA and additional lens is not critical (up to several tens of centimeters).
The full fan angle of Top-Hat generation for GTH-4-2.2FA is 2.2 mrad. This leads to Top-Hat sizes:
- 110x110 µm for lens with f=50 at 50 mm distance
- 220x220 µm for lens with f=100 at 100 mm distance
- 2.2x2.2 mm for lens with f=1000 at 1000 mm distance
- 4.4x4.4 mm for lens with f=2000 at 2000 mm distance
