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

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

We will exhibit the world largest dichroic mirror for the KCRM/Keck, uniquely machined dichroic mirrors for the LLAMAS/Magellan, or patterned filter with 4 colors on single surface. And we will introduce the state-of-the-art UV transmission filter, high transmission custom IR filter, SDSS and UBVRcIc filter set (all dielectric coating version) by posters.

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

We will exhibit the following items at the site.

• SDSS filters (All dielectric coating)
• UBVRcIc filters (All dielectric coating)
• Dichroic beam splitters
• UV transmission filter
• All dielectric broad band mirror
• Custom IR filters
• Large filters
• Patterned filter
