Recognized by professionals in imaging! Compact color camera × Fisheye lens

Report on the combination of CIS's compact 4K/FULL HD cameras and fisheye lenses for various applications such as VR shooting, monitoring, investigation, and inspection.

The image processing algorithm ISP "Clairvu," developed independently by CIS, adjusts colors and brightness to create natural-looking images, achieving high quality that is well-regarded by professionals in the field. The CIS-made 4K and FULL HD cameras, designed with a compact size and robustness cultivated through industrial camera development, are equipped with SONY global shutter CMOS, enabling distortion-free imaging. By using these cameras along with fisheye lenses, it becomes possible to simplify the entire system, achieving space and cost savings while also enabling high-quality imaging. 【Entaniya Fisheye HAL 200/250】 - Designed for VR shooting, it has low peripheral compression, allowing for sharp rendering and straightforward stitching. - Specifications that minimize issues such as vignetting, aberration, and image flow. - With an ultra-wide angle of 250°, it enables one-shot VR without stitching lines. 【OPTART FJ SERIES】 - 185° fisheye lens compatible with 1/2” 2-megapixel megapixels. - Specifications that significantly improve resolution in both the center and periphery. - Well-suited for aerial photography and security fields where high precision is required.

Micro Lens Array Plastic Lens

Micro Lens Array Plastic Lens

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.

Leave the molding and processing of Fresnel lenses to us!

Leave the molding and processing of Fresnel lenses to us!

Fresnel lens considering workability and lens efficiency.

Fresnel lenses are used in a wide range of fields, but due to their fine and complex shapes, ultra-precision machining technology is required to manufacture them. Characteristics of Fresnel Lenses Conventional lenses are formed into spherical, aspherical, or free-form surfaces to change the direction of light and focus or diffuse it. However, Fresnel lenses achieve a thin and lightweight design by dividing the lens into concentric rings and creating steps, allowing them to retain the function of "bending light" while eliminating unnecessary thickness. Additionally, large-diameter lenses that are difficult to achieve with conventional lenses can be relatively easily manufactured with Fresnel lenses. In terms of applications, they are used in many fields due to their thin and lightweight characteristics, as well as their ability to focus and diffuse light, such as in projectors, lighting, and VR/AR-related technologies. For more details, please proceed to the URL!

[For Developers and Designers] From a single prototype. Custom sensor lenses.

[For Developers and Designers] From a single prototype. Custom sensor lenses.

Consistent support from optical design to molds and molding. We address the challenges of cost reduction, weight reduction, and mass production by providing alternatives to glass.

"While we want to ensure the performance of the sensors, cost and weight are challenges... We need complex shapes that are difficult to achieve with glass lenses... Since we are in the development stage, we would like to prototype in small lots first." Do you have such concerns? We specialize in the injection molding of plastic lenses and respond to our customers' diverse needs. Our strength lies in our integrated production system, which allows us to complete everything in-house, from optical design to mold making, molding, coating, and evaluation. This enables us to shorten development lead times and reduce costs. Our precise molding technology can also achieve high precision for complex shapes such as aspheric and freeform lenses.
