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. Because their optical components are placed precisely
through the use of high-precision machining, the blocks shield light
superbly. Also, you can use the separate blocks in different combina-
tions by removing and attaching them with thumbscrews.

The A10030 series is an adapter block for connecting a PMT module to a V-
groove type optical block.
This block connects a device having C-mount to V-groove type optical
blocks. The connection angle for the device and block is adjustable.
Optical fiber cables with FC or SMA connectors can be connected to the
blocks in the A10037 series.
The lens assembled in the block collimates the light spread from the optical fiber.
This optical block widens the diameter of a collimated beam of light to 2.5
times its original size or narrows the diameter to 1/2.5 times its original size.
The A10038 series is a joint block for connecting one optical block to
another. The joint is available in two types: MM (male-male) type and FF
(female-female) type.
This holder block is a small dark box specifically designed for cuvettes with
an optical path length of 10 mm, and allows easy measurement of samples
in combination with various optical blocks.
The A10036 is a manual shutter block with a plate that is opened and
closed by sliding it left and right. Light is sufficiently blocked so there will be
no problem even at photon counting levels.
A neutral density (ND) filter is included in this optical block to attenuate light
levels.
This optical block contains a filter that passes only particular wavelengths.
Bandpass filters and long-pass filters are available.
The A10033-90 is a holder block for assembling a commercially available
15 mm diameter filter.
This block contains a dichroic mirror that reflects particular wavelengths but
passes other wavelengths. A total of six products are available.
This optical block uses a cubic type half-mirror. Incident light is split into
reflected and transmitted beams at a ratio of 1 to 1.
The A10035-90 is a holder block designed to hold a 15 mm cubic type
beam splitter.
This is a dark box equipped with 2 micrometers for positionings. It allows
light measurements even under room lighting by externally connecting vari-
ous types of optical blocks.
This optical block is for using an infinity-corrected objective lens to guide
laser light into an optical fiber with an attached FC connector or to collimate
and transmit the beam from a fiber-optic cable.
This block contains a focusing lens with a focal distance of 100 mm and is
used for an infinity-corrected objective lens. Aberration is reduced due to
the use of an achromatic lens.
This is a feed screw type holder block that can hold a commercially available,
mount type pinhole and adjust its position in the XY direction. Light passing
through the pinhole is collimated by the lens installed in the block and is output.
The A11213 series is a C-mount connection block for installing a commercial-
ly available 25 mm diameter filter or lens. This block allows angle adjustment
and so is useful as a spacer or adapter that connects between C-mounts.

This ring is for connecting a PMT module to a optical block and an equip-
ment with C-mount.
The A11214 is a C-mount connection block for installing a dichroic mirror for
use at a 45° angle of incidence.
This is a holder block designed for a polarizer.
Polarizing filters and waveplates are polarizing elements whose polarization
characteristics change depending on direction and angle.
This maintenance kit includes a set of screws and O-rings needed to as-
semble optical blocks.

1. Loosen the four screws
on the adapter block
and make sure the C-
mount ring is separated
about 1 mm from the
adapter block body.
2. Insert the C-mount ring
into the C-mount of the
PMT module and turn
the adapter block body
clockwise until it stops.
3. Turn the adapter block
body counterclockwise
so that it is positioned
at the desired angle
and then tighten the
four screws.
