Business Details
A segment handling optical component parts covering a wide range of applications from research and development to industrial use. Composed of three product groups: Basic Optical Equipment Products (stages, holders, etc.), Automated Application Products (automated positioning units, alignment systems, etc.), and Optical Elements & Thin-Film Products (mirrors, lenses, filters, etc.). Main customers include universities and research institutions in Japan and overseas, the electronic components/semiconductor-related electronics industry, and the bio industry, with offerings ranging from catalog sales to one-off custom orders and medium-volume OEM production. Characterized by global expansion through overseas subsidiaries in the U.S., Europe, and Asia. In the current fiscal year, a China procurement subsidiary (Shanghai Sigma Integrated International Trading Co., Ltd.) was added to the scope of consolidation.
Recent Overview
Net sales increased slightly, but operating income decreased slightly due to sluggish demand for optics for electronics applications
In the Component Parts Business for FY2026 (ending May 2026), net sales including intersegment sales were ¥9,831 million (up 0.8% year on year), while operating income decreased slightly to ¥1,636 million (down 0.4% year on year). The price revision effect, strong performance of alignment systems, and resolution of inventory adjustments for bio-microscope stages contributed positively, but sluggishness in lenses, mirrors, and similar products for major customers in the electronics field weighed on results. The environment remained challenging through the third quarter but improved from the fourth quarter onward. In the current period, the China procurement subsidiary (Shanghai Sigma Integrated International Trading Co., Ltd.) was added to the scope of consolidation, strengthening the global production system.
Key Products
Growth Drivers
- Expected recovery in demand for Optical Elements & Thin-Film Products against the backdrop of a recovery trend in demand from the electronic components/semiconductor industry
- Increasing trend in demand for alignment systems related to photonic integrated circuits (PIC) and optical-electronic convergence
- Continued recovery in demand from industrial fields in overseas regions (the U.S., China, Southeast Asia, etc.)
- Improvement in sales unit prices through continued price pass-through, mainly for catalog sales products
- Strengthening of the global production and procurement system through the consolidation of Shanghai Sigma Integrated International Trading Co., Ltd.
- Firm trend in demand from research and development fields such as universities and government institutions in Southeast Asia, centered on quantum-related fields
- Solid performance of bio-microscope stages for the bio industry following resolution of inventory adjustments
Risks
- Risk of continued sluggish demand for lenses, mirrors, and similar products used in embedded applications for manufacturing and inspection equipment for major customers in the electronics field
- Decline in profit margin due to increased personnel expenses and depreciation associated with expanded human capital and capital investment
- Impact on overseas demand from uncertainty surrounding U.S. trade policy (reciprocal tariffs) and heightened geopolitical risk
- Foreign exchange fluctuation risk (foreign currency-denominated transactions associated with global expansion)
- China business risk (deterioration in the business environment for Shanghai Sigma Koki Co., Ltd. and Shanghai Sigma Integrated International Trading Co., Ltd.)
- Risk of recurrence of inventory adjustments by major customers in the bio industry

Business Details
A segment providing high-quality systems cultivated through production technology for component parts and a track record in the laser optics field. Handles laser system products, Bio & Medical-Related Products, and Optical System Products for both research/development and industrial applications. Main customers include the electronic components/semiconductor-related electronics industry, the medical industry, and the defense industry. The segment is centered on Optical Unit Products and Optical System Products used in embedded applications for manufacturing and inspection equipment, and adopts a build-to-order production system.
Recent Overview
Net sales declined 11.1% year on year on soft demand, but operating income improved significantly, up 52.5%
In the System Products Business for FY2026 (ending May 2026), Optical Unit Products and Optical System Products used in embedded applications for manufacturing and inspection equipment for the electronics industry were generally soft. In the medical industry, demand for assembly projects related to radiation measurement increased, but overall performance was weak due to a decline from the previous year's large-scale diagnostic equipment assembly projects, among other factors. Optical System Products for the defense industry performed solidly. Net sales including intersegment sales were ¥1,707 million (down 11.1% year on year), while operating income improved significantly to ¥111 million (up 52.5% year on year).
Key Products
Growth Drivers
- Continued solid demand for Optical System Products for the defense industry
- Expected continuation of the recovery trend in the electronic components/semiconductor-related electronics industry from the second half of FY2026 (ending May 2026)
- Expected recovery in demand for Optical Unit Products and Optical System Products used in embedded applications for manufacturing and inspection equipment in the electronic components/semiconductor industry
- Increased demand for assembly projects in the medical industry related to radiation measurement, among others
- Promotion of global expansion of high-value-added optical module and Optical Unit Products
- Expansion of product planning and development through collaboration with companies in growth industry fields (quantum, aerospace, nanotechnology, etc.)
Risks
- Risk of continued soft demand from the electronic components/semiconductor-related electronics industry
- Risk of sales fluctuation due to a decline from major customer projects (medical industry, etc.)
- Uncertainty over demand due to geopolitical risk surrounding U.S. trade policy (reciprocal tariffs)
- Risk of profit pressure due to increased external costs such as material costs and outsourced processing costs
- Risk of fluctuation in order backlog associated with the build-to-order business model
