Features & benefits

Hamamatsu Photonics has been undertaking fundamental research, development and manufacture of a wide range of Spatial Light Modulators for well over 30 years at the Central Research Laboratory and Solid State Division factory in Hamamatsu City, Japan. From early ferroelectric and twisted nematic Liquid Crystal constructions to optically and electrically addressed versions, Hamamatsu Photonics has consistently been the foremost leaders in the design and manufacture of Spatial Light Modulator products.  Furthermore, all parts of each LCOS-SLM is designed and manufactured in-house at the factory, thus allowing each LCOS-SLM to be individually optimized to your laser and application.

Key features and benefits of the Hamamatsu X10468 LCOS-SLM series

Feature Benefit
High Light Utilization Efficiencies (up to 95%) This means that the overall efficiency is high, (Higher reflectivity and lower diffraction noise) with consequences of being able to perform higher levels of correction and it corresponds to a higher power handling capability
Pure, Phase Modulator with > 2π modulation and very linear  
The average linearity error (π) is 0.0057 (RMS)
Improvement of spatial resolution and phase depth means that a wider dynamic range of correction can be achieved. Easy to set up and use. No calibration required.
High Diffraction Efficiencies Unwanted intensity of the zero order light is greatly reduced over intensity of first order and higher order diffraction spots
Very Low Phase Noise Highly time-stable phase shifts and no significant fluctuation of the zero order and the first diffraction order intensities are observed when addressing making this device ideal for laser machining applications
Very High Phase Stability
(eg < 0.007 π, peak to peak at 633 nm)
The advantage of the SLM being driven by a highly stable voltage (rather than digitally addressing the pixels) means that it has a very good stability of < 0.03 λ, important for pulse shaping applications (e.g. Quantum Optics)
CMOS Backplane, FAB and Optical Thin Film Technology all conducted in-house at Hamamatsu’s factories Allows greater control, flexibility, customization and optimization for the manufacture of each SLM taking into account your application
Models with dielectric mirror coatings and ceramic packaging Higher laser damage thresholds opens up the SLM to laser material processing applications enabling higher throughputs and higher efficiencies thereby reducing operating costs
8 LCOS-SLM models covering 355 – 1550 nm and OEM versions available Flexibility for using many different types of readout lasers and applications
High Fill Factor (98%) Less undesired diffraction losses from the surface
Excellent Flatness:
PV (peak to valley): 0.04 λ (1/20 λ)
RMS: 0.005 λ
Standard deviation (SD): typ. 0,0036 (π)
Excellent phase modulation uniformity and significantly reduced wave front distortions
Pixel gap of only 0.2 microns Due to small pixel gap, this has a direct consequence of a high utilization efficiency due to the low diffraction losses from the CMOS backplane
Up to 120 Hz DVI Frame Rate Over an order of magnitude faster than previous models, opens up new Adaptive Optics and Laser Processing applications
Powerful and efficient SLM controller Compensates for phase uniformity and wavefront distortions and allows linearity corrections
Unique Look Up Table supplied with each SLM Optimization to your readout laser’s wavelengths and operating conditions. Ensures linear phase response.
DVI Interface Quick to set up using easy to use and practical computer interface
50 W, weight: 420 g (head), 3.4 kg (controller) Low power consumption, lower operating costs
Well established and proven world leader in the design and manufacture of optical and opto-electronic components and systems since 1953 Geared up for large scale manufacture of LCOS-SLMs and ability to provide customization and optimization of SLMs depending on your application
