PHOTO RESEARCH Equipment We Repair — By Category
PHOTO RESEARCH Product Lines We Repair
Our engineers are trained on the full PHOTO RESEARCH product range. Below are the major product families we service.
PR-655/670 Spectroradiometer Series
Handheld spectroradiometers for colour and light measurement in displays, lighting, and automotive applications. Common issues include sensor drift, optical window contamination, calibration loss, and USB communication failures after extended field use.
PR-745 Display Photometer
Precision photometer for LCD and OLED display characterisation. Typical faults involve photodiode degradation, optical lens calibration drift, and firmware corruption affecting measurement accuracy in production lines.
PR-730 and PR-740 Spectraview Series
Advanced colour analysis systems for broadcast, cinema, and display verification. Repair challenges include AGC (Automatic Gain Control) circuit failures, wavelength calibration loss, and data logger malfunction in harsh manufacturing environments.
Photo Research Optical Sensors and Probes
Replacement sensor heads, optical windows, and measurement probes for all Photo Research instruments. Common issues include mechanical connector wear, optical coating degradation from dust or chemical exposure, and photodiode sensitivity loss in high-humidity factory conditions.
Photo Research Software and Interface Modules
Legacy RS-232 and USB interface cards, calibration software, and data acquisition modules. Typical failures include corrupted firmware, driver incompatibility with modern Windows systems, and EEPROM corruption affecting stored calibration constants.

Common PHOTO RESEARCH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in PHOTO RESEARCH equipment arriving at our workshop.
- ✓Spectroradiometer shows unstable or drifting readings — Photo Research spectroradiometers rely on precision optical alignment and CCD/CMOS sensor stability. Thermal drift, vibration during transport, and contamination of the optical path (dust on lens, window fog) cause measurement instability. Calibration constants stored in EEPROM degrade over time, especially in high-humidity Indian manufacturing environments.
- ✓USB or RS-232 communication failure with PC — Photo Research legacy spectroradiometers use older USB chipsets or RS-232 UART circuits prone to driver conflicts on modern Windows 10/11 systems. Cold solder joints on interface PCBs, corroded connector pins from workshop humidity, and firmware version mismatches cause dropout or no-detection errors.
- ✓Colour measurement readings no longer match reference standards — Photo Research display photometers and spectrometers lose calibration when optical sensors age, window coatings degrade from handling or chemical cleaning, or internal calibration lamps fail. In Indian factories with high dust and temperature variation, photodiode sensitivity shifts and wavelength reference drifts out of spec within 2-3 years.
- ✓Measurement probe physically damaged or cracked optical window — Photo Research probe heads are fragile optical assemblies. Accidental drops, impacts during transport, or chemical cleaning agents crack the borosilicate window or misalign the internal lens stack. This is common in busy automotive component testing labs across Gujarat, Maharashtra, and Tamil Nadu.
- ✓Instrument powers on but display is blank or shows error code — Photo Research LCD displays fail due to age, LCD driver IC faults, or power supply rail collapse. Onboard firmware may be corrupted, causing boot loops or blank screens. Power supply filter capacitors dry out in hot Indian factory conditions, reducing voltage regulation.
- ✓Inconsistent measurement results across multiple instruments — Photo Research instruments require periodic cross-calibration and verification against reference standards. Without proper maintenance, spectral response variations between units grow, causing colour mismatch complaints in multi-shift automotive or display manufacturing lines.

Frequently Asked Questions — PHOTO RESEARCH Repairs
Do you repair Photo Research equipment anywhere in India?+
Yes. Synchronics repairs the full Photo Research portfolio — spectroradiometers, display photometers, optical sensors, and measurement probes — across India. We offer PAN India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Gandhinagar, and all other industrial cities. Equipment is transported securely to our Vadodara, Gujarat facility, where our 180+ engineers perform diagnostics, repair, and factory-standard calibration before return.
How do Photo Research spectroradiometers get out of calibration in Indian manufacturing?+
Photo Research instruments rely on stable optical alignment and photodiode sensitivity. Indian factory conditions — high dust, temperature swings between 15°C and 45°C, vibration from machinery, and humidity spikes — cause thermal drift and contamination. Without annual recalibration, spectral accuracy degrades within 18-24 months. Synchronics recalibrates using traceable reference standards and issues NIST-aligned calibration certificates.
What is your typical Photo Research repair turnaround time?+
Standard Photo Research repair turnaround is 10-15 working days from receipt. Spectroradiometer calibration and optical alignment take 5-7 days. If replacement components (probe heads, optical windows, interface modules) are required, lead time may extend 3-5 days. We offer express 5-day service for critical production line equipment. Door pickup and delivery are included PAN India.
Can you repair legacy Photo Research PR-730 and PR-740 instruments?+
Yes. Synchronics specialises in legacy Photo Research instruments, including PR-730, PR-740, PR-745, PR-655, and PR-670 models. We maintain archive firmware, sourced OEM replacement components (AGC circuits, sensor heads, calibration lamps), and hold calibration reference data. Many Indian automotive and display manufacturers still operate these instruments in production; we keep them operational.
Do you provide calibration certificates for repaired Photo Research equipment?+
Yes. All Photo Research instruments are returned with factory-equivalent calibration certificates traceable to NIST standards. We document spectral response, colour accuracy, wavelength calibration, and linearity performance. Certificates are valid for 12 months from repair date and are accepted by Indian automotive OEMs and display manufacturers as proof of compliance.
How do I send my PHOTO RESEARCH unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a PHOTO RESEARCH drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on PHOTO RESEARCH repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your PHOTO RESEARCH unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
