Modulation characteristics
- No modulation: possible in all models
- TTL modulation up to 100 KHz: ZN-TTL, ZV-TTL
- Analogue intensity control: ZN-ana, ZV-ana
- MHz-range modulation e.g. for synchronization with pixel read-out frequency: ZN-HM, ZV-HM

Focus distance
Fixed focus
- all models except ZV and ZPT
Every fixed focus laser will adjusted by our production on your stated focus. If a variable focus is required, we recommend following models:
Hand focusable
ZV
Tool adjustable
ZPT
|
|
|
|
|
|
|
|
|
|
|
Active temperature control
Necessary, if high wavelength-stability is required.

Power
- up to 5 mW: all models
- up to 30 mW: all models (except ZB)
- up to 100 mW: ZN, ZV, ZPT and ZQ
- up to 1.5 W: ZQ

Power supply
Integrated power supply:
ZPT
Plug-in power supply :
ZB, ZD, ZN, ZV, ZQ
Please note:
Power supplies have no modulation function. In case you need TTL modulation or analogue intensity control, you have to care yourself for an appropriate frequency modulator resp. an adjustable power supply.
