It is a precision measuring microscope that measures the distance between two points, such as hole diameter, thickness, and width.
This is a measurement device that utilizes the principle where two optical images, a direct image and an inverted image, appear to have a deeper color when they are in contact or overlap with each other, using edge contact.
This is a microscope designed to observe the underside in the depth direction!
The main body can be attached to a 3D micro-stage, allowing for fine adjustments to any observation position. (All L-type microscopes are the same.) It appears three-dimensional, making it easy to see the differences in the surface contours of the observed object. The lighting uses fiber and halogen light sources, enabling bright observations.
This is an easy-to-use microscope that allows you to switch between bright and dark field images using fiber ring lighting and coaxial lighting by rotating a knob!
This is an easy-to-use microscope that allows for switching between bright field and dark field images by rotating a knob, using fiber ring lighting and coaxial lighting. The bright field image is similar to what you would see with total reflection illumination in a metal microscope, while the dark field image resembles what you would see with reflected illumination. Two types of images with different properties can be observed with this microscope. You can obtain two different views of bright and dark fields with one device, expanding its usability.

The "CW-01" is a glass that has no variation due to wavelength and uniformly diffuses light. It is a milky white phase-separated glass that can be used as a diffusion plate. The transmission light distribution has a Lambertian characteristic, with a flat transmission rate curve extending from the visible to the infrared range. Shapes and dimensions can be approximately square with sizes from 5 to 100 mm, and round with sizes from 5 to 150 mm. 【Features】 ■ No variation due to wavelength, uniformly diffuses light ■ Usable as a diffusion plate ■ Flat transmission rate curve from the visible to the infrared range *For more details, please refer to the PDF document or feel free to contact us.
Achieving high-precision cutting (drilling, grooving, engraving) of difficult-to-process brittle materials such as glass and ceramics, as well as new materials.
Prosonic's ultrasonic processing machine features a high-performance "ultrasonic spindle" that combines ultrasonic vibrations with high-speed rotation of diamond drills. The intermittent contact between the drill tip and the workpiece surface due to ultrasonic vibrations not only enhances processing accuracy but also provides synergistic effects on the processing machine itself and tool life. ● Specializes in small-diameter deep holes with excellent straightness - Maximum length of 500mm. Capable of deep hole processing with an aspect ratio of 1:100 (drill diameter: depth) depending on the drill diameter. ● Improvement of surface roughness - The minute vibrations of ultrasonic waves transmitted to the drill's outer diameter in contact with the workpiece reduce the crushing layer on the cutting surface. ● Enhanced removal of sludge (chips) - The cavitation of the cutting fluid caused by ultrasonic vibrations improves the removal of sludge. ● Extension of drill life - Intermittent contact between the drill and the workpiece delays the degradation and wear of the drill. We offer optimal proposals tailored to customer needs, including standard machines, customized machines, and special orders.

Our scan lenses are based on the latest optical design and offer both telecentric and non-telecentric types. They cover a wide range of wavelengths including 266 nm, 355 nm, 532 nm, 1064 nm, and 10.6 µm, and possess diffraction-limited performance. The internal optical elements have no back reflection spots and are made from materials such as synthetic quartz, CaF2, and sapphire to withstand high-power lasers, with a laser endurance exceeding 6 KW. Additionally, these lenses have a very high uniformity of the focal spot at over 95%, and in the case of telecentric lenses, the telecentricity error is kept below 1°. The focal lengths range from 32 mm to 920 mm, and the scan field can accommodate sizes from 6 x 6 mm to 710 x 710 mm. Options for water cooling and air cooling are available. Furthermore, the optical coatings feature low-reflectivity AR coatings, with reflectivity typically kept very low at R<0.2%.

It is possible to measure the angle-dependent reflectance near an incident angle of 0°.
In general, the measurement of reflectance near 0° incident light cannot be performed because the rotating arm on the receiving side obstructs the incident light axis. This device can measure the angle-dependent reflectance at 0° incident light.

This is a lens used for a wide range of applications such as laser printers and laser processing.
The "fθ lens" from Daikyo Manufacturing is designed to ensure that the scanning speed is constant between the peripheral and central areas of the lens by changing the curvature of the combined lenses. The name comes from the relationship where the focal length is f, the incident angle is θ, and the image height Y is related by Y = fθ. ◆ We can make your specifications for fθ possible by designing it to meet requests that could not be achieved with off-the-shelf products! While maintaining the positional relationships of existing equipment, we aim to increase productivity for customers who want to: - "Expand the drawing area" - "Reduce the processing spot diameter," etc. We will respond to your requests! - We will customize the design and manufacture according to the applications of customers who find standard products insufficient in terms of spot size, drawing area, wavelength, etc. - Customers considering performance improvements with your products or processing machines are also welcome to contact us. 【Features】 ■ Scanning performance is better than non-telecentric systems ■ Large lens diameter
