DLP6500FLQ: Availiability with UV laser

Taeseung Hwang

Part Number:

Hi all,

I've planned to use the DLP6500FLQ with UV laser (wl: 349nm, power: 150mW(max), 15mW(min)). The recommended illumination power (Total combined <420nm: 0.68mW/cm^2) was much smaller than our power density(9.65 ~ 96.5mW/cm^2). Related to the power issue, I have several questions below.

1. If we use a 349nm laser source, what would happen on DMD? (e.g., Intensity drop due to the anti-reflection coating degradation)

2. Is the recommended illumination power applied for a laser? I'm quite skeptical for this value since I heard other guys were fine when they used a white source with a color filter(385nm, 50mW/cm^2). 

3. I'd like to get your opinion about using 349nm as our laser source with DLP6500FLQ.

4. Can I get a refund if I cannot use the DLP6500FLQ with our laser?

Please let me know if you have any questions or need further information to answer my questions! Thank you!

Best,

Taeseung

    Hello Taeseung,

    The DLP6500FLQ will not work is not intended to work with a UV laser--this DMD is only intended for visible light spectrum (400 nm to 700 nm). I am unable to answer whether or not it would actually work, even with filtering.

    I am unable to answer your remaining questions because the application is outside the scope of this DMD and we would not be able to refund you if the DMD is used outside of its intended specifications. I'm very sorry I could not give you a better answer on this, Taeseung.

    I am unaware of any of our customers using it this way, but that is something they have developed using their own filters, and we cannot support this. It would have to be R&D on the customer's end.
