Optics schematic and information

Justin Haag

Is a schematic of the optics available? Also, is the projected image angled upward as is standard in consumer projectors, or does it project straight out (symmetric about optical axis)?

Thank you,

Justin

    Hello Justin,

    I encourage you to contact Young Optics International for information on optics schematic. And, the image projected by LightCrafter is angled upwards.

    Regards,

    On Table 1-1 of the LightCrafter User's Guide there are some optical specifications. The trwo ratio is 1.66 and the image is offset 100% upward. This allows lying the system on a table and projecting above the table.

    Best regards,

    Hi Divya,

    I've sent multiple emails to Young Optics over the past couple of weeks, but have received no response. Do you have contact information for someone there that might have this information?

    I am basically interested in collimating the output beam from the LightCrafter. One question I had was as to what the depth of field of the projector is. By that I mean, since the image plane is currently optimized for an off-axis projection, how bad would the focus of a projected image be after attempting to collimate the beam?

    This is probably the major drawback I've found in attempting to use TI's DLP development kits in scientific application. There seems to be no easy answer to fix it other than using custom optics. However, to design custom telecentric optics requires the use of TIR prisms, which seem to be difficult to come by. I also emailed Young Optics regarding obtaining a prism, to no avail.

    Thank you for your help,

    Justin

    Hi Justin,

    We regret that you have not yet received a response from Young Optics.  As a original design manufacturer (ODM), Young Optics provides integrated design and manufacturing services with a focus on projection light engines for end products.  You may also want to consider one of our DLP Design Houses with experience in optics.  A complete list of DLP Design Houses, including capabilities, can be found here.

    The DLP projectors and development kits have been developed with an image offset for projection purposes. The optics has to be aligned with the DMD axis to achieve collimation.  Unfortunately, LightCrafter's optics is not designed for this purpose and it did not employ a TIR prism. As I have mentioned, you might want to consider one of our DLP Design Houses.

    Thanks & Regards,

    Divya
