OPTO OPTICAL BLOCKS
Optical Components for Optical Measurement
The optical blocks are compact units that contain components such GEasy to Attach / Detach
as bandpass filters and dichroic mirrors. They are designed for low- GNo Alignment Required
light-level measurements that use PMT modules and high-sensitivity GSuperb Light-shielding Effect
cameras. Because their optical components are placed precisely GMakes Low-Light-Level
through the use of high-precision machining, the blocks shield light
superbly. Also, you can use the separate blocks in different combina- Measurement Easy
tions by removing and attaching them with thumbscrews.

Adapter Block The A10030 series is an adapter block for connecting a PMT module to a V- 4
A10030 Series groove type optical block. 5
C-Mount This block connects a device having C-mount to V-groove type optical 6
Adapter Block blocks. The connection angle for the device and block is adjustable. 6
Optical fiber cables with FC or SMA connectors can be connected to the 7
Fiber Adapter Block blocks in the A10037 series.
A10037 Series The lens assembled in the block collimates the light spread from the optical fiber.
Beam Expander Block This optical block widens the diameter of a collimated beam of light to 2.5
A10031 times its original size or narrows the diameter to 1/2.5 times its original size.
Joint Block The A10038 series is a joint block for connecting one optical block to
A10038 Series another. The joint is available in two types: MM (male-male) type and FF
Cuvette Holder Block
A11971 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
Shutter Block 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.
ND Filter Block A neutral density (ND) filter is included in this optical block to attenuate light
A10032 Series levels.
Filter Block This optical block contains a filter that passes only particular wavelengths. 8
Bandpass filters and long-pass filters are available.
Filter Block The A10033-90 is a holder block for assembling a commercially available 9
A10033-90 15 mm diameter filter.
Dichroic Block This block contains a dichroic mirror that reflects particular wavelengths but 10
passes other wavelengths. A total of six products are available.
Beam Splitter Block This optical block uses a cubic type half-mirror. Incident light is split into 11
A10035 reflected and transmitted beams at a ratio of 1 to 1.
Beam Splitter The A10035-90 is a holder block designed to hold a 15 mm cubic type 11
A10035-90 beam splitter.
Stage Block This is a dark box equipped with 2 micrometers for positionings. It allows 12, 13
A10858 light measurements even under room lighting by externally connecting vari- 14
ous types of optical blocks.
Beam Aligner Block
A10760 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
