Our LCOS-SLM uses parallel-aligned, nematic liquid crystals, and uses a CMOS backplane for the addressing. They are reflective devices.
Yes, the whole system including the CMOS backplane and optical thin film is designed and manufactured in-house by HAMAMATSU. This means that the LCOS-SLM is optimized to the laser wavelength.
We have a range of LCOS-SLM to cover wavelengths between 355 nm and 1550 nm.
Yes. As mentioned above, all parts of the LCOS-SLM are designed in-house at the HAMAMATSU factory, meaning that there is a higher degree of flexibility with regard to providing customized LCOS-SLM. Please contact us with your exact requirements, and we’ll see what we can do.
No, all LCOS-SLMs are delivered with a linear phase characteristic, and an individual flatness correction data is provided.
We use carefully designed control electronics to electrically drive the LCOS chip. Consequently, the phase fluctuations and flickering are negligible. For further information, please consult us and we can provide further details.
The total light utilization efficiency is determined by the reflectivity of LCOS-SLM and also by the circuit loss that is caused by the pixel structure. The reflectivity is determined by the mirror characteristics. Besides the aluminum mirror type, we provide the dielectric multilayer mirror type (02/-03/-04/-05/-06) with high reflectivity up to 97%. The diffraction loss is dependent on the pixel size, fill factor and liquid crystal material of LOC-SLM. The high fill factor achieves a good diffraction efficiency.
No, all you need is to use a standard graphics card with a DVI output. Ideally, use a card with two ports to have the control on a monitor and the LCOS-SLM on the 2nd port.
It depends if you use the LCOS-SLM (-01/-07/-08 type) with an aluminum mirror or the (-02/-03/-04/-05/-06 type)with the dielectric mirror. The latter can withstand much higher CW and pulsed laser powers. We tested several lasers, and you can find the results in the LCOS-SLM Technical Information (ask us for a copy). If your special laser parameters are not listed, please ask us and we are happy to help ensure you use the LCOS-SLM safely.
Yes, we can provide you with a demo system. You can then use the LCOS-SLM in your lab and test its performance directly within your setup. Please contact us to discuss your experiment and arrange the schedule. This demo loan is free of charge for you. We kindly ask you to send it back to our office and summarize your findings on completion of the loan.
Price lists are not available. Please contact our sales office for the price of the spatial light modulator of your interest.
The standard delivery time will depend on the manufacturing cycle. The typical lead time is six to eight weeks from receipt of order though sometimes deliveries can be shorter than this, and we do hold some LCOS-SLM in loan stock should something be urgently required.
The standard warranty is 12 months from receipt of product.
