We offer THz lenses made of TPX and HRFZ-Si.

1.  TPX Lenses
 
Commom specification: 
 
Material TPX
Typeplano-convex, bi-convex
Available diameters, mm to 100
Diameter tolerance, mm + /-0.25
Claer aperture, %>=90
EFL tolerance (for lenses), % +/- 1
Surface quality (two-sided polishing), scr/dig 80/50
Surface accuracy, mm
+/- 0.01 deviation from ideal sphere and plane
THz lenses

The following TPX lenses are available from stock:

No. Diameter EFL
mm inches mm
1 25.4 1.0 25.0
2 25.4 1.0 50.0
3 25.4 1.0 100.0
4 25.4 1.0 200.0
5 38.1 1.5 50.0
6 38.1 1.5 75.0
7 38.1 1.5 100.0
8 38.1 1.5 150.0
9 38.1 1.5 200.0
10 50.8 2.0 50.0
11 50.8 2.0 75.0
12 50.8 2.0 100.0
13 50.8 2.0 150.0
14 50.8 2.0 200.0

*All EFLs are calculated for wavelength 300 µm. EFL deviations related with refraction index dispersion at the edges of THz range (30-3000 µm) and within visible range are negligible in comparison with EFL tolerances manufactured.

Please check Optics stock.
Alternate sizes (max thickness 30 mm) and custom design are manufactured upon request.

2. HRFZ-Si Lenses
 
We offer HRFZ-Si lensesof different types: hyper-/hypo-/hemispherical, bullet, and meniscus.

Common specification:
 
Material HRFZ-Si
Typespherical, hyper-hemispherical,
hemispherical,
hypo-hemispherical, and bullet
Available diameters, mm
2-100
Dimensions tolerance, mm +/-0.1
Clear apperture, % >=90

CoatingAR coatings upon request
THz lenses

The polished 'ball-shaped' blanks of HRFZ-Si (with diameters 2.0, 4.0, 6.0, 8.0, 10.0, and 12.0 mm) are always in stock. Upon your request hyper-/hypo-/hemi-spheres will be supplied within 2 weeks as the flat surface of the lens can be polished for the required thickness.
