DLP7000 Mirror Surface Reflectivity at 850nm

Other Parts Discussed in Thread: DLP7000

Hello,

Would you please give us DLP7000 "mirror surface reflectivity" at 850nm wavelength? Furthermore, its "mirror array diffraction efficiency" at 850nm wavelength as well. I know these factors are varied by wavelength.

Regards,
Takeshi

    Hello Takeshi-san,

    The mirror surface reflectivity closely follows that of bulk aluminum, there are many great resources available for bulk aluminum reflectivity across wavelength ranges, let me know if you have trouble finding one with data in your desired range.

    The DLP7000 datasheet lists the Array Diffraction Efficiency as 86% in the Features section on the first page. As you noted, this factor will vary across wavelengths. Unfortunately, we do not have exact data available that spans our operating wavelengths at this time.

    I hope this helps!

    Regards,

    Trevor
