LITUPLITUP Technology
MICRO OPTICS FOR EEL PACKAGING
LITUP designs and supplies sub-millimetre silicon 45° micro turning mirrors. They redirect the horizontal beam of an EEL into vertical emission, so the laser leaves the TO-CAN and moves into low-profile SMD or COB packages placed by standard SMT equipment.
IN-HOUSE PRODUCT
Silicon 45° mirror, gold or aluminium surface, General (mR) and Optical (uR) grades. Nominal geometry H 460 / PW 250 / s 160 / W 250 µm, designed for pick-and-place and with anti-wicking edges for die attach.
Specifications and FAQWHO IT IS FOR
Send us the wavelength, submount height, emitting distance and package envelope. We reply with the mirror material, grade and whether the acceptance angle covers your divergence — before any sample is shipped.
LITUP also provides custom adhesive formulation and technical service; that service is currently available to customers in Taiwan.
HOW WE WORK
We do not start from a catalogue. We start from how the problem occurs in your package, then decide what the mirror has to meet.
Laser, submount, emitting distance, package and acceptance criteria written down first.
Mirror material and grade chosen against measurable targets and tolerances.
Samples, process window and failure criteria arranged so data maps to a production decision.
Takt, equipment compatibility and supply terms confirmed before ramp.
INTERACTIVE TOOL
Enter wavelength, fast/slow-axis divergence, submount height and emitting distance. The simulator returns the geometric acceptance of the 45° mirror and the gold/aluminium reflectance, and converts FWHM ↔ 1/e². No contact needed to find out whether your laser fits; results are for package evaluation, not a delivery guarantee.
