Laser modules with 520 nm laser diodes that emit directly are being used more and more in medical technology – quite often as a replacement for 532 nm solid-state lasers. All FLEXPOINT® laser modules are now available with 520 nm laser diodes.
The 520 nm FLEXPOINT® modules are also equipped with a photodiode, which offers the following advantages:
Performance Stability across a Given Temperature Range
The output power is kept constant at ±5% – across the entire operating temperature range between 0°C and 50°C. Comparable modules achieve only ±10%. Due to this level of stability, we can guarantee compliance with critical laser classes.
Single Fault Safety
An additional monitoring circuit guarantees real single fault safety: this is absolutely crucial in the medical field.
Power Adjustment and Modulation
The output power can be adjusted analogously using a control wire and a voltage signal (0-5 V). The photodiode significantly improves the linearity of the adjustment range. In addition, we offer the option of digital or analogous modulation, as well as pulse width modulation.
The 520 nm laser modules are available as dot, line, or cross-hair lasers. The output power ranges from <1 mW to 25 mW. The laser modules can be modified and adjusted according to customer specifications.
These lasers are used to position patients in CT or MRT applications and as pilot beams in high-power medical lasers.
