We promise to design and manufacture objective lenses with high precision, ensuring reliable technical expertise.
The objective lens is the most important optical component that determines the basic performance and functionality of optical pickups. It plays a crucial role as a lens that focuses laser light down to a sub-micron order spot to read digital signals (pits) on optical discs. Our company has established a system to produce high-quality products and provides objective lenses with stable quality.
We promise to design and manufacture collimator lenses that meet your needs.
A collimator lens is a lens that parallelizes the light emitted from a semiconductor laser. It is used in various components such as CD players and laser pointers, playing a very important role. Therefore, meticulous design is essential to meet the customer's applications and preferences.
Feel free to consult us regarding the specification design and manufacturing stage of sensor lenses.
When receiving the light returned from the optical disc with a light-receiving element, it is necessary to make the spot shape elliptical. Therefore, this lens has one side shaped like a cylinder (kamaboko shape). We provide sensor lenses that fully meet our customers' needs.

We will conduct scratch assessment on 200×100 mm square orange lenses (plastic lenses)!
Inquiry regarding scratch assessment for 200×100 mm square orange lens (plastic lens). There are requests for scratch assessment of plastic lenses, assessment of plastic molded product dents (depressions), assessment of plastic laser printing, and other appearance inspection requirements. In the initial stage, a free simple verification will be conducted, followed by guidance for paid verification. 【Inspection Settings and Results】 We verified whether scratches could be detected using the image inspection software EasyInspector. As a result, detection was possible, but false detections occurred in other areas depending on the type of scratch, making it impossible to detect "only defective scratches." With our product, the AI image inspection software "DeepSky," which uses AI (deep learning) capabilities, the AI can automatically adjust the setting parameters and recognize only the scratches as the target object. Therefore, it is recommended as it is less affected by changes in appearance due to lighting variations. 【Software Used】 Software used: EasyInspector710 Currently, EasyInspector2 also has AI capabilities and supports various inspections. We will propose solutions tailored to the inspection target.
Aspherical lenses are lenses that continuously change the curvature in the radial direction.
Aspherical lenses are lenses that continuously change their curvature in the radial direction. This allows for the correction of spherical aberration (blurring of light), which would require multiple spherical lenses, with just one lens, and enables the realization of short focal lengths. Sankei Co., Ltd. has achieved a shape accuracy of 0.1 to 1 μm or less in mold processing to accommodate the plasticization of these aspherical lenses. Furthermore, thanks to accumulated know-how, we have achieved mass production. For more details, please contact us or refer to our catalog.
Micro Lens Array
A micro lens array is a collection of lenses arranged by placing multiple single lenses side by side both vertically and horizontally. Generally, it refers to single lenses with an outer diameter of about φ1mm or less, and due to its appearance, it is sometimes called a fly eye lens. It is mainly used in lighting optical systems to split a single light source into multiple secondary light sources and to overlap multiple light beams from these secondary sources to achieve uniform illumination. Our diffuser lens has this MLA structure. When the size of the single lens is smaller than 1mm, it is common to use photolithography technology for manufacturing; however, we produce them by ultra-precision cutting of molds and using resin injection molding technology. *For more details, please feel free to contact us.
