BLOCK CHARACTERISTICS
GPinhole Holder Block A11027
The A11027 is a holder block for mounting a pinhole. The screws can
be used to adjust the pinhole's position in the XY directions. The built-in
lens collimates the light that passes through the pinhole and converges
the light on a photodetector.
There is a base attached to the holder block through the M3 screw
holes in the bottom of the block. If necessary, this base can be re-
moved and re-attached to the side of the block.

NOTE: • The collimate status changes depending on the pin-
hole diameter and the wavelength. (The assumed
wavelength is between 400 nm and 700 nm.)
• The pinhole is not included. Use a pinhole that is in-
stalled in a mount. (Products by companies such as
SIGMA KOKI CO., LTD.; SURUGA SEIKI CO., LTD.;
and CVI Melles Griot can be used.)

• Be careful to install the pinhole so that it faces in the
correct direction.
• When installing a pinhole, be careful to keep it clean
and to avoid getting fingerprints on it.

Extended Example of Microscope
Connecting the A11027 pinhole holder block to the C-mount port of a
microscope configures a confocal optical system. Light passing
through the pinhole is collimated by the lens in the block and is effi-
ciently guided to the PMT module.
