Lasers & Light Sources

Optosigma Lasers and Light Sources provide calibrated illumination for optical experiments, spectroscopy, interferometry, and microscopy. They range from compact diode laser modules to stabilized DPSS and He-Ne gas lasers.

Diode laser modules:
– Wavelengths: 405 nm, 445 nm, 488 nm, 520 nm, 635 nm, 660 nm, 785 nm, 830 nm, 980 nm, 1064 nm
– Output power: 1 mW to 500 mW depending on wavelength and model
– Beam quality: single-mode (M2 below 1.2) or multi-mode options
– TTL modulation input; analog modulation for intensity control
– Integrated driver and TEC temperature stabilization in compact module

DPSS (diode-pumped solid-state) lasers:
– 532 nm green: 1 mW to 500 mW; narrow linewidth for Raman spectroscopy
– 1064 nm Nd:YAG: CW and Q-switched pulsed versions
– Low noise: RMS noise below 0.5% for interference and holography

He-Ne gas lasers:
– 632.8 nm; highly stable frequency; low beam divergence
– Powers from 0.5 mW to 35 mW
– Long coherence length; used for holography, interferometry, alignment

Broadband and LED light sources:
– Halogen 150 W: broadband 400-2500 nm for spectroscopy and illumination
– LED arrays: narrow bandwidth; stable intensity for fluorescence excitation
– Fiber-coupled output: SMA or FC/PC connector

NewRoad provides Optosigma lasers and light sources in Israel for optical labs, spectroscopy, holography, and fluorescence microscopy.
