Shutter Options; Mounting A Smartshutter In A Lambda Ls - Sutter Instrument LAMBDA 10-B Operation Manual

2.7 Shutter Options

The LAMBDA 10-B can drive a wheel-mounted shutters or one or two standalone
SmartShutters. If wheel-mounted shutter, the shutter can be either a Sutter Instrument
SmartShutter or a Uniblitz shutter; whereas if two SmartShutters, then no filter wheels is
allowed. In the case of the wheel, it can be either a one inch or a 32 mm wheel. A wheel with
a SmartShutter installed will attach to the DB-25 connector on the back of the controller. A
wheel with a Uniblitz shutter attached will connect via the DB-15 connector on the rear of
the controller.
CAUTION: Do not attempt to connect more than one shutter or one wheel. Do not try to
use both the DB-25 and the DB-15 connector at the same time, except when connecting a
standalone filter wheel (no integrated shutter) and a standalone
which is not integrated with a filter wheel). If you do not have a shutter, use the
connector that matches the type on the wheel.
The controller will detect the SmartShutter, if installed. The controller will assume that
there is a Uniblitz shutter if no SmartShutter is detected.

2.8 Mounting a SmartShutter in a Lambda LS

The one-inch stand-alone version of the SmartShutter can be mounted inside current
versions of the Lambda LS. A male-to-male c-mount adapter is used to couple the
SmartShutter to the C-mount block inside the Lambda LS. Stacking c-mount extension tubes
are threaded into the other side of the SmartShutter to provide an enclosed light path from
the SmartShutter to light port on the Lambda LS.
The stacking c-mount extensions that have been used in the past add 1 inch of length beyond
the male threads. These pieces are stepped down in outside diameter so that they can slip
inside a dovetail tube just as the lens tube does. The overall length of these tubes will be
reduced by 0.070 inches so that two tubes stacked will fit between the SmartShutter and the
external wall of the Lambda LS. These pieces will still be usable in conjunction with the
dovetail tube to enclose the light path when no shutter or a Vincent shutter is installed.
Until new parts are available, a single tube cut down by 0.14 inches can be stacked with a 1-
inch tube.
Since the Lambda LS does not have any inherent capability of controlling the SmartShutter,
an externally positioned LAMBDA 10-B (or another Lambda model capable of controlling a
SmartShutter) can be used to control the SmartShutter. Additionally, the LAMBDA 10-B can
be used to control one or two filter wheels, one of which may be installed inside the Lambda
LS, and another, which may be installed on the external part of the Lambda LS cabinet.
