Kimmon Koha Co.

What Kimmon Koha Co. does

Kimmon Koha Co., Ltd. (株式会社金門光波) is a Tokyo-based (Ota-ku) specialty laser manufacturer whose origins trace to 1884, with the laser business established in 1971 and the current corporate entity spun off in 2005. It designs and manufactures gas, fiber, and CO2 lasers — principally helium-cadmium (He-Cd) lasers at 325nm UV and 442nm blue wavelengths, patented UV fiber lasers at 318nm, a premium scientific-grade fiber laser (KKFL-20), and a 25W–450W CO2 laser oscillator series — with cumulative shipments exceeding 46,000 He-Cd units since 1971.

The company serves scientific research laboratories, industrial manufacturers, and semiconductor-related customers, with the He-Cd line used in applications such as interferometry, photoluminescence, and semiconductor inspection. Revenue is generated through direct and distributor-mediated hardware sales plus after-sales service and warranty support. Distribution is anchored by Marktec Corporation (a subsidiary of TSE Prime-listed Alconix Corporation), which acts as sole general agent across Asia-Pacific, Europe, and North America; the company also operates Kimmon Koha USA directly.

Since 2022, Kimmon Koha has operated as a wholly-owned subsidiary of Marktec Corporation, providing corporate scale and capital access. The firm employs 11–50 people, reflecting a niche specialty manufacturer rather than a high-volume industrial supplier. In 2024 it received the 16th Laser Society Industry Award and launched its CO2 Laser Oscillator product family, signaling a deliberate diversification beyond the mature He-Cd core.

Core offering

Kimmon Koha Co. is a Japanese laser manufacturer that designs, assembles, adjusts, and inspects lasers entirely in-house. It produces continuous-wave Helium-Cadmium (He-Cd) gas lasers (325nm, 442nm, and dual-wavelength), UV fiber lasers (318nm, 100mW), Premium scientific-grade fiber lasers, and RF-excited CO2 laser oscillators (25W–450W) for scientific, semiconductor, and industrial customers. The company has shipped over 46,000 He-Cd laser units worldwide since 1971 and sells through Marktec Corporation and a global distributor network.

Product overview

Kimmon Koha Co. is a laser hardware manufacturer offering three main product lines: He-Cd (Helium-Cadmium) gas lasers (the company's longest-running line since 1971 with over 46,000 units sold), fiber lasers (including UV Fiber Lasers at 318nm and Premium Fiber Lasers for scientific use), and CO2 laser oscillators (new product line with RF-excited models from 25W-450W). The company maintains complete in-house manufacturing control over design, assembly, adjustment, and inspection. Accessory products include power meters, optical mounting feet, cooling fans, and power supplies.
