Optical blocks(23)

The optical blocks are compact units that contain components such as bandpass filters and dichroic mirrors. They are designed for low light level measurements that use PMT modules and high-sensitivity cameras.

Scan block(1)

The C10516 scan block is an optical block that combines galvano scanners with a telecentric fθ (F-theta) lens designed for laser beam scanning in the visible range.

FOP (fiber optic plates)(13)

The FOP is an optical device comprised of a bundle of micron-sized optical fibers. The FOP is used as a lens to convey the light and image with high efficiency and low distortion.

FAC lens(1)

The J10919 series FAC lens is an optical lens that collimates light spreading from a semiconductor laser in the fast-axis direction. Semiconductor lasers have a large divergence angle in the fastaxis direction, so the output light cannot be efficiently used unless collimated. The FAC lens collimates light spreading from a semiconductor laser into a narrow beam with a radiation angle of several milliradians (mrad) or less so that the diverging light can be efficiently utilized.

Collimating capillary lens(1)

The J12432-01 capillary lens is an optical element for X-rays, consisting of a bundle of numerous hollow glass capillaries formed into a cylindrical shape with one end gently tapered.

Capillary plates(12)

Capillary plates have excellent linearity and high precision yet offer selectable directivity, making them suitable for flow control and particle sorting, etc.

Flow cells(1)

For over 50 years we have manufactured glass vacuum devices such as photomultiplier tubes, which require special quartz glass processing, high accuracy, optical polish, etc. We have applied this extensive experience and knowledge to manufacturing flow cells.

LCOS-SLM (Optical Phase Modulator)(27)


The LCOS-SLM (Liquid Crystal on Silicon-Spatial Light Modulator) is a reflection type spatial light modulator that freely modulates the light phase as needed. A light beam such as a laser beam entering the LCOS-SLM is phase-modulated and then reflected to freely control the wavefront of (reflected) light as needed. This ability to accurately control the light wavefront makes the LCOS-SLM ideal for applications such as optical beam pattern forming and aberration correction. The LCOS-SLM is the ideal partner for a wide range of applications that include laser processing, laser marking, fundus imaging by corrective optics, optical tweezers utilizing optical manipulation techniques, femtosecond laser pulse shaping, and a host of other fields.

Image splitting optics(2)

Image splitting optics

The image splitting optics provides one pair of dual wavelength image to cameras.

MEMS mirror(1)


MEMS mirror are an electromagnetically driven mirror that incorporates our unique MEMS (micro-electro-mechanical systems) technology. We achieved an ultra-miniature scale by mounting the magnet beneath the mirror. Within a magnetic field generated by the magnet, electrical current flowing in the coil surrounding the mirror produces a Lorentz force based on Fleming’s rule that drives the mirror. Hamamatsu MEMS mirrors offer a wide optical deflection angle and high mirror reflectivity as well as low power consumption.

SERS substrate(1)


The surface-enhanced Raman spectroscopy (SERS) substrate enhances the Raman scattering light from molecules, making high-sensitive Raman spectroscopic analysis possible. A chip of metallic nano/sub-micro structure is mounted on Hamamatsu’s original handling plate to protect its active area. The active area of the handling plate is of a well structure for easily attaching solution or the like. It is noted this is a disposable product and cannot be reused.
