The Model S48D Illumination Source is housed in a
single full width (16.73 inches wide X 6 inches high X 18.7 inches deep) rack mountable
chassis. It weighs 27.5 pounds. The C&L Dye Fluorometer's innovative
filter wheel design and reasonable cost distinguish it from the competition. For a
more general discussion of this product, refer to our Product
Overview page.
Overview
- The Model S48D Illumination Source uses a fully digital control scheme to provide
precise timing and accurate positioning of a filter wheel for wavelength selection.
It is the ideal source for multiwavelength photometry and fluorescence imaging.
- This illumination source requires either the PC-C, PC-DAQ, or RS-DAQ Instrument
Controller to operate. The S48D can be programmed to output up to eight wavelengths
in any sequence using an eight position filter wheel. The duration of illumination at any
wavelength filter position can be programmed to be continuous or to vary from 1
millisecond to several seconds.
- This illumination source contains a light attenuation wheel for precise control of light
output intensity. Each wavelength position can be programmed to have a unique light
intensity. This is ideal for multiwavelenght and multi-dye applications.
- The S48D contains a software-controlled shutter.
- Adapters are
available to interface the Model S48D to a variety of microscopes as well as a cuvette module.
- Light is output using either a 3mm or 5mm core
diameter quartz liquid light guide. Fiber optic bundles are also available on
request.
Specifications
Modes of control
- The Model S48D is operated using one of three instrument controllers, the Models PC-C, PC-DAQ, or RS-DAQ Instrument Controller. Several operation modes
are selectable to permit numerous protocols from single wavelength measurements to
multiwavelength measurements. Together with the Model D48
Detector Module, all combinations of single and multiwavelength excitation and
emission protocols are available.
- Jitter of the filter wheel when spinning is <0.5 percent (RMS) of the filter aperture
time.
- Time to reposition filter wheel from one stationary position to any other stationary
position is < 60 milliseconds for an 8 position filter wheel.
Accessible filter wheel
- The S48D can hold either a 4 or 8 position filter wheel. The 4 position wheel uses
1 inch (or 25 mm) diameter filters, while the 8 position wheel uses 1/2 inch diameter
filters.
- The filter wheel is easily removed from Model S48D to make rapid filter wheel changes
possible.
- Additional filter wheels can be purchased and configured for special wavelength
combinations.
Internal Shutter
- An internal shutter is provided.
- The shutter is controlled by software.
150 or 300 Watt xenon arc lamp
- Replacement lamp is a prealigned unit.
- Capable of high power output (5.8 Watts with 300 Watt lamp).
- Light output is from approximately 300 to 700 nm.
Control of light Intensity
- The S48D contains a computer-controlled light
attenuator wheel for precise control of output light intensity over a 50-fold range.
- The output can be attenuated equally for all filter
wavelength positions or each wavelength position can be set individually.
