RatioMaster Photometer Description from HORIBA
When you need to perform microscope photometry, what do you use? Most labs end up acquiring some microscope accessory intended for another purpose—such as photography.
Unfortunately, these devices are rarely up for the task. Microscope photometry requires absolute light-tightness. It also helps to have a device designed to accommodate a photomultiplier housing—or even two. Additionally, it should hold filters, have an adjustable iris, and provide a means to view the image being measured.
Our microscope photometers do all of this—and more. They are specifically designed for sensitive photometric measurements. And they couple easily to virtually any popular microscope.
No system is complete without an analog/digital photon counting detector. In order to complete a PTI RatioMaster system, an analog/digital photon counting detector, selected from only our best quality and performing photo-multipliers, the 814 series.
Analog/Digital Photon Counting
Model 814 is a compact PMT housing for analog or digital (photon-counting) detection. The detection mode is switchable, and the built-in LCD can also selectively display high voltage or analog signal level. Features power on/off switch, high voltage adjust, LCD high voltage/analog signal display, detection mode and display mode switches, gain, time constant and offset adjustment controls, BNC signal output connection, BNC external high voltage adjust input connection, light-tight RF shielded case, internal direct anode output mode control, and socket for most 1-1/8 inch side-on photomultiplier tubes. Includes a separate wall-mount line voltage power supply. This detection system excels at applications like the following:
Live-cell imaging
High-speed emission ratio imaging
Quantitative FRET, FRAP, FISH
Luminescence
Analog Mode:
This mode can be used for medium to high levels of light intensity. The maximum PMT current is 10 microamperes. The output is a DC signal between +13 Volts and -13 Volts.
Photon-Counting (Digital) Mode:
This mode can be used for low to medium light levels up to 4 million counts per second. The output is a TTL level, active low signal. The signal line must be terminated at 50 ohms. The output is a frequency corresponding to the number of photons impinging on the photocathode.

Model 814 PMT Housing
Model 814
is a compact PMT housing for analog or digital (photon-counting) detection. The detection mode is switchable, and the built-in LCD can also selectively display high voltage or analog signal level.
Features power on/off switch, high voltage adjust, LCD high voltage/analog signal display, detection mode and display mode switches, gain, time constant and offset adjustment controls, BNC signal output connection, BNC external high voltage adjust input connection, light-tight RF shielded case, internal direct anode output mode control, and socket for most 1–1/8 inch side-on photomultiplier tubes. Includes a separate wall-mount line voltage power supply.
Analog Mode:
This mode can be used for medium to high levels of light intensity. The maximum PMT current is 10 microamperes. The output is a DC signal between +13 Volts and -13 Volts. This signal is usually measured with a voltmeter, a recorder, or the analog-to-digital converter in a general-purpose I/O board in a computer.
Photon-Counting (Digital) Mode:
This mode can be used for low to medium light levels up to 4 million counts per second. The output is a TTL level, active low signal. The signal line must be terminated at 50 ohms. The output is a frequency corresponding to the number of photons impinging upon the photocathode, and is usually measured with a counter in a general-purpose I/O board in a computer.
Direct PMT Output Mode:
This mode applies the signal from the photomultiplier anode directly to the output BNC. This is generally used only when the highest-speed response is desired. Internal digital or analog signal processing is completely bypassed. The peripheral equipment connected to the housing must be properly configured to accept the signal directly from the PMT itself.
