ProductSLM-200SLM-210SLM-250SLM-300

Do you have reflectance data for the AR coating of LCOS-SLM?SLM-200SLM-210

Yes, we can provide reflectance data. Please contact us.

Q.Is it possible to specify the frame rate for LCOS-SLM?

Yes, please select 60Hz/120Hz when ordering.
(You cannot switch frame rates after purchase.)

Q. Is wavefront correction data available for LCOS-SLM?

Yes, the wavefront correction data is stored in the included USB memory stick. Note that ambient temperature and mounting method will affect the wavefront.
(If you purchased before March 2021, the data is not stored. Please contact us for more info.)

Q. Do you have labview vi files for LCOS-SLM?

Yes, a sample of the SDK (Labview) is stored on the included USB memory stick.The SLM SDK for Windows can be downloaded from here.

Q. Do you have CAD data for LCOS-SLM?

Yes, we can provide CAD data. Please contact us.

Q. Do you have a water-cooled chiller? What products do you recommend and what are your requirements?SLM-300

Unfortunately, we are unable to provide a water-cooled chiller, but the requirements are as follows. Please help us in the selection process.
Joint : Rc(PT) 3/8 inch female
Flow rate :1-2L/min

Q. What kind of spatial optical phase modulator is LCOS-SLM?

LCOS-SLM is a spatial light phase modulator that allows free manipulation of light by electrically controlling the amplitude, phase, and polarization of light. The liquid crystal mode is VA orientation and the drive is analog voltage drive. For more information on the principle, technology, and characteristics, please refer to here.

Q. Was the LCOS-SLM developed in-house?

Yes, everything from system design to manufacturing is done in-house. Therefore, the LCOS-SLM is optimized for each wavelength of the laser.

Q. In which wavelength bands is the LCOS-SLM suitable for use?

We offer products in the wavelength range of 365-1600 nm. You can choose the product that corresponds to the light source used.

SLM-200SLM-210 : Products are available in the 450-1600nm wavelength range. 
SLM-250 : UV wavelength range (365-550nm) is available.
SLM-300 : Three wavelength bands (532nm, 800nm, and 1064nm) are available according to the wavelength of the laser to be used.

Q. Is customization support available?

Flexible customization to meet your requirements is available. Please contact us.

Q. Do I need to measure phase characteristics and flatness before actual use to correct for individual device phase characteristics and flatness?

No, you do not need to measure. We ship LCOS-SLMs with excellent linearity phase characteristics. We also provide individual wavefront correction data with the product.

Q. How phase stable is the LCOS-SLM?

The phase stability is among the best in the world, with excellent characteristics of less than Typ. 0.002 pi. The controller that drives the LCOS chip has been carefully designed to minimize fluctuations.

Q. Do I need a special interface to drive the LCOS-SLM?

No, you do not need to provide an interface. Only a standard graphics card with DVI output is required to drive the LCOS chip.

Q. At what level does laser damage would occur?

Depends on laser specifications (wavelength, average power, pulse energy, pulse width, repetition rate), please contact us for more information.

SLM-300 : 200W/cm^2

Demo unit

Q. Is it possible to rent a demo unit for evaluation?

Yes, it is possible. Please contact us to arrange a schedule. The loan period for demo equipment is usually two weeks. Upon return, we will ask you to submit a questionnaire. For more details, please click here.

Price, Delivery, Warranty

Q. Is there a price list for the LCOS-SLM?

Unfortunately, we do not provide a price list. Please contact us for pricing on the spatial light modulator of your choice.

Q. What is the lead time for the LCOS-SLM?

Standard lead time is 6-8 weeks after placing an order. Depending on manufacturing conditions, we may be able to deliver sooner than normal. If you are in a hurry, please let us know.

Q. What is the warranty period for the LCOS-SLM?

Warranty period is 12 months after delivery.
