It has superior optical performance compared to spherical lenses and is primarily used in imaging systems and similar applications.
"Aspherical lenses" have superior optical performance compared to spherical lenses and are primarily used in imaging systems and similar applications. The main manufacturing methods include "cutting and polishing" and "press molding." Our company can propose suitable methods based on quantity, cost, and shape. It is also possible to apply anti-reflective coatings according to the specified wavelength.

Company information
We handle a wide range of optical products. ◆◆◆ Optical Thin Films (Coatings) ◆◆◆ We own nearly 10 small to continuous deposition devices, capable of handling "almost all optical thin films." With low-temperature deposition devices (IAD), we can also work with resins and special glass materials. We are confident in our quality and appearance. The biggest difference is our possession of three automatic cleaning devices, allowing for effective differentiation! In recent years, we have been focusing on various functional films such as "static prevention," "water repellency," and "dirt resistance." ◆◆◆ Core Drilling Processing ◆◆◆ We can perform core drilling on spherical lenses with diameters starting from 0.5mm. Our high-precision processing using bell clamps has a long-standing track record with major camera manufacturers. We also handle deburring and outer diameter corrections. ◆◆◆ Optical Components ◆◆◆ We manufacture spherical lenses, prisms, flat plates, etc., according to customer specifications. We provide inspection data for high surface accuracy and high parallelism. We also accommodate bonding and composite products (such as combinations with metals). ◆◆◆ Main Clients ◆◆◆ We serve clients in camera lenses, laser optical systems, imaging optical systems, lighting optical systems, and analysis/measurement devices. We cater to researchers needing prototypes as well as large manufacturers for mass production. For inquiries, please feel free to contact Kato at h-kato@taisyou-op.co.jp.
