DLP3000 without window

Hello,

I am under the impression, both from the datasheet and by inspecting the unit, that there is a thin glass window glued on top of the mirrors in the DLP3000. I see that it is possible to buy the mirrors independent of the lightcrafter (http://www.digikey.com/product-detail/en/DLP3000FQB/296-30917-ND/3053244), but is it possible to buy a DLP3000 without the window?

Thank you,

Logan Clark
