Product Description
EG&G PARC 1229 Spectrograph and 1454 Detector – Optical Multichannel Analysis System
This used EG&G PARC (Princeton Applied Research Corporation) system consists of a Model 1229 Spectrograph coupled with a Model 1454 Detector, forming a complete optical multichannel analysis (OMA) system for spectroscopy applications.
EG&G PARC was a legendary manufacturer of scientific instrumentation, particularly known for their Optical Multichannel Analyzer (OMA) systems that revolutionized spectroscopy in the 1970s-1990s. Their instruments were standards in research laboratories worldwide.
About EG&G PARC OMA Systems
The OMA (Optical Multichannel Analyzer) concept, pioneered by PARC, allowed simultaneous detection of multiple wavelengths using array detectors, dramatically speeding up spectral acquisition compared to scanning monochromators. A typical OMA system included:
-
Spectrograph: Dispersed light onto the detector array
-
Detector: Multichannel detector (diode array, CCD, or similar)
-
Detector Controller: Electronics for detector operation
-
Console/Computer: Data acquisition and analysis
The Model 1229 Spectrograph was likely a compact instrument designed for use with PARC’s detector series. The Model 1454 Detector was probably a silicon photodiode array (PDA) or similar multichannel detector, typical of the OMA era.

System Components
| Component | Status |
|---|---|
| EG&G PARC 1229 Spectrograph | Included |
| EG&G PARC 1454 Detector | Included (coupled to spectrograph) |
| Detector Controller | [Not included – requires external OMA controller] |
| Data Acquisition Console/Computer | [Not included] |
| Cables/Interconnects | [Not included unless specified] |
⚠ CRITICAL NOTE: This system includes the spectrograph and detector head only. It requires an external OMA controller (such as EG&G PARC Model 1460, 1461, or similar) and appropriate cables for operation. The detector cannot function without its dedicated controller.
