Series E photodetectors are eye-response detectors that use the successful Series 5T chip together with high-quality glass colour-correcting filters. Their spectral response approximates the human eye, making them ideal for general photometric applications.

The Series E range is colour corrected to provide a photopic response, which makes it well suited for low-cost illuminance monitoring in instrument and industrial environments. These detectors are available in several package sizes and active areas, with standard products available from stock.
Key Features:
- Eye-response spectral behavior for photometric use.
- Built on the proven Series 5T chip.
- High-quality glass colour-correcting filters.
- Suitable for low-cost illuminance monitoring.
- Multiple active areas and package options available.
- Standard products generally available from stock.
Applications include general photometric applications, low-cost illuminance monitoring, instrument lighting measurement, and industrial illuminance sensing.
