All our TO headers are available
- without cap: not recommended
- with cap without window: mechanical protection of laser chip, e. g. during installation in setup
- with cap with window: mechanical protection of laser chip, e. g. during installation in setup, hermetically sealed capsule, protection of laser chip from dust, water vapour, oxygen and other harmful impacts
For our TO5 and TO66 workhorses, we offer
caps with black interior coating and antireflection coated windows: minimization of back reflection of the window, optimized antireflection coating for each wavelength.
