DLP4500: LWIR Properties of the DLP4500 series

Lars Dreyer

Part Number: DLP4500
Other Parts Discussed in Thread: DLPC350,

Hello altogether!

Is it possible to exchange the window (which is transparent in the visible and NIR spectrum) through a window which is transparent in the infrared (5-11µm wavelength)?

Do you have any results about the reflectivity of the aluminum coating in the LWIR(5-11µm)?

Does the DLP4500FQE automatically come with a controller?

Best,

Lars

Hi Lars,

There is no option to exchange the windows on the DMDs unfortunately. Sorry!

The DLP4500FQE does not have a controller built in, you also need to purchase a DLPC350.

Thanks!
Paul

Hello Paul,

did you do any research on the reflectivity in the LWIR-spectrum (5-11µm)?

Right now, the NIR window only supports out to 2500nm (2.5um). We have not studied beyond that range.

Sorry I got two more follow-up-questions regarding your device:

The window of the DLP4500 is just for protective reasons against dust particles?

Or is there a vacuum in the space between window and the micro mirrors?

Thanks,

Lars

Hi Lars,

The window serves as protection, a wavelength filter, and has proprietary chemistry between the windows and the micro mirrors.

Best,

Paul
