Optical elements
Optical elements and units
Materials that are permeable to infrared rays are often difficult to process and handle. Furukawa Denshi tackles these issues to meet the demands of customers through expertise built up over many years. In recent years, our products have been adopted for use in components destined for government ministries and agencies.
