Asahi will be back to the exhibition at SPIE Astronomical Telescope + Instrumentation in June!

We have continued to provide high quality astronomical filters or dichroic mirrors to well-known observatories or telescopes since the last 2018 SPIE meeting in Austin.

We will exhibit the largest ever dichroic mirror for the KCRM/Keck, uniquely machined dichroic mirrors for the LLAMAS/Magellan, or patterned filter with 4 colors - g, r, i, z band - on single surface. (All are replica) And we will introduce the state-of-the-art UV transmission filter, high transmission Y, J, H, K filter, SDSS and UBVRcIc filter set with all dielectric coating version by posters.

We are very willing to discuss with you about challenging inquiries and build challenging optics for next-generations instruments together. Stop by our booth #323 and ask the feasibility of what you need for your science!
