NTKJ Co., Ltd. is pleased to announce our attendance for

SPIE Astronomical Telescopes + Instrumentation 2024 in Yokohama, Japan

from 18th – 20th June, 2024.



Highlights of NTKJ at the Exhibition – Ultra precise optics & components with micro structure 

With NTKJ’s Freeform TL 1000 of AMETEK/Precitech, an ultra precision machining system NTKJ now has wide variety of precision optics manufacturing capability from large scale to small with pico-order precision. 

With the machine which has diamond turning and micro milling capability and with NTKJ’s technique utilising the system with 50-year experience in optics manufacturing, NTKJ’s customers will benefit to source precise optics and components from NTKJ for various applications such as not only in opto-electronics but also spectral analysis, defense, sensing and so many other fields.

NTKJ, the Ultra-Precision optics manufacturer, is also capable of handling UV, VIS, IR wavelength range. NTKJ’s 10 pico-meter resolution of 5+2 axis enable to manufacture customized optics for various defense and sensing application up to 5000mm diameter.

Examples presented is a large 300mm aperture of diamond turned “Aluminum mirror”.
