SCT 320 Description

This manual is intended to help you set up and operate your new IsoPlane SCT 320

spectrograph. Even if you are an experienced user of spectroscopic equipment, we suggest

that you follow the manual (at least initially) to insure proper setup and operation. If you

have any questions about the information contained in this manual, contact the Princeton

Instruments customer service department. Refer to Contact Information on page 82 for

complete contact information.

The IsoPlane SCT 320 (IsoPlane) is a 320 mm focal length spectrograph. Its advanced

optical design reduces astigmatism to zero, increasing spatial and spectral resolution

dramatically over traditional spectrographs. Large-diameter optics and interchangeable

triple-grating turrets permit operation from the UV to NIR with extremely low light levels at

high, low or intermediate spectral resolution. IsoPlane includes 32 bit microprocessor

controlled scanning, built-in USB and RS-232 interfaces, and a micrometer-controlled

entrance slit. In addition, it has a direct digital grating scan mechanism with full wavelength

and grating control capabilities. The IsoPlane works seamlessly with Princeton Instruments'

industry-leading CCD, EMCCD, ICCD and InGaAs array detectors and Princeton

Instruments' LightField

®

with IntelliCal™ and WinSpec data acquisition software

packages. Figure 1-1 illustrates a typical IsoPlane SCT 320.

1.1.1 External Power Supply

Figure 1-2 illustrates a typical IsoPlane power supply with an inset providing the pin

locations for the power connector. Refer to Table 1-1 for specific pinout information.

Figure 1-2: IsoPlane Power Supply

1.1.2 Data Cables

The following computer cables are included with the IsoPlane:

• 3650-USB-06 USB Cable Type A to Type B.

• CC-499-2 IBM AT or compatible 9-pin female (DB9S) connector to 9-pin male

connector (DB9P).

If neither of these cables is compatible with the host system, contact Princeton Instruments

about obtaining a custom cable. If you have facilities for building a custom cable, refer to

the RS-232 pin assignments listed in Table 1-1. Additional information in available in

Appendix D, RS-232 Interface, on page 71.

1.1.3 Grating Turret

Each IsoPlane is shipped with, and includes, one grating turret.

NOTE:

Additional turrets are available from Princeton Instruments. Refer

to Section C.2, Triple-Grating Turrets, on page 63, for ordering

information.

SpectraSense is a comprehensive spectral acquisition and data treatment

package. It is designed to work exclusively with Princeton Instruments’

products and accessories, including the SpectraHub Detector Interface.

SpectraSense software will control and acquire data from both single channel

detection systems, which require scanning of a monochromator, and

CCD-based detection systems that may or may not require repositioning of a

spectrograph.

Chapter 2: Entrance Slit Accessories

Princeton Instruments offers a full range of spectrograph accessories that mount directly to

the IsoPlane’s manual or motorized entrance slit assembly.

NOTE:

Princeton Instruments spectroscopy accessories include

customized installation procedures for their proper mounting and

operation. Always refer to accessory-specific documentation for

complete installation and operation information.

Figure 2-1, which illustrates a manual slit assembly, may be helpful when mounting an

accessory to the IsoPlane.

2.1 Mount an Accessory

In general, the procedure to mount an accessory to the entrance slit is:

1. Place the accessory directly against the face of the slit body.

2. Using four (4) 8-32 screws typically provided with the accessory, secure the accessory

to the slit body.

Light sources fitted with light collection/focusing optics are normally factory-aligned to the

standard slit.

NOTE:

In some instances with light sources, there is limited access to the

bottom two screw holes. In this case, Princeton Instruments

provides special slotted holes in the light source housing to

facilitate mounting the source to the slit.

2.2 Slit Width Adjustments for Manual Slits

NOTE:

Information in this section applies to the following manual slit

models:

• 716-1 Manual Bilateral Slit;

• 716-MS Kinematic Slit.

The slit width of each bilateral slit assembly (716 type) is adjustable from 0.010 mm to

3 mm (10 µm to 3,000 µm) by a micrometer knob located on the top of the slit housing. The

micrometer knob is graduated in 0.010 mm (10 µm) increments.

Each clockwise revolution of the micrometer knob increases the slit width 0.25 mm

(250 µm.) For maximum reproducibility, the slit width should be set in a clockwise

direction (i.e., increasing slit widths,) each time it is changed. See Figure 2-2 and

Figure 2-3.

CAUTION!

!

The micrometer knob should not be rotated below a reading of

0.00 nor above 3.00. A micrometer setting of less than 0.010 mm

(10 µm) should not be used, because a stop is provided to prevent

the slit jaws from contacting each other.

Damage may occur if slit jaws are opened more than 3.0 mm.

2.3 Slit Width Adjustments for Motorized Slits

The Model 718-1 motorized slit assembly is a

self-calibrating, 10 µm to 3 mm adjustable bilateral slit.

Stepping-motor-controlled adjustments are made in 1 µm

increments over the full range. The Model 718-12 motorized

slit assembly is a self calibrating, 10 µm to 12 mm adjustable

bilateral slit. Stepping-motor controlled adjustments are

made in 5 µm increments over the full range.

Full control of the slit, including automated bandpass setting,

is integrated into LightField

®

and SpectraSense™ software.

The slit motor is energized only when you send a command

via the software to control it. When spectrograph power is

turned off, the slit remains in the position to which it was last

set. This position is stored in nonvolatile memory allowing

slit position to be maintained with power on or off.

Chapter 3: Grating Turrets

This chapter provides information about the installation and removal of grating turrets on an

IsoPlane spectrograph.

3.1 Turret Installation

If you have just received an IsoPlane spectrograph, you will need to install the grating

turret. The grating turret has been shipped in the same shipping box with the IsoPlane but is

packaged in a plastic container outside the IsoPlane housing to protect the gratings during

shipment.

CAUTION!

!

1. The optical surfaces in the spectrograph are extremely

delicate and can be permanently damaged by contact with

solid objects as well as with most liquids and aerosols.

2. DO NOT TOUCH optical surfaces with anything. Wear

thin protective powderless gloves to minimize damage from

body oils if you accidentally touch any optical surface,

especially the grating.

3. Avoid talking or sneezing near optical surfaces. Do not

breathe directly on them.

Figure 3-1 identifies the location of the Grating Turret for an IsoPlane.

Perform the following procedure to install a grating turret into an IsoPlane unit:

CAUTION!

!

Observe proper optical handling procedures.

REFERENCES:

Refer to Section 3.3, Turret Interchange, on page 21 for

information about replacing one turret assembly with another.

1. Locate the storage container with the grating turret that is to be installed.

2. Using the 9/64” hex wrench, remove the four Turret Compartment cover screws and

remove the cover. Become familiar with the grating turret and its components.

3. Before removing the grating turret from the shipping container, use a 3/32” hex wrench

to loosen the three set screws on the bottom of the container (about 1 turn.)

4. Remove the cover from the shipping container, grasp the Center Torque Screw and turn

it counter-clockwise until the turret can be lifted straight up. See Figure 3-2.
