Photodiode Arrays (PDA) for Scientific Applications
AMI Semiconductor's WS and HS series are two distinct families of linear self scanned photodiode arrays. These photodiode sensors employ AMI Semiconductor's proprietary CMOS image sensing technology to integrate the sensors into a single monolithic chip. They are optimally designed for applications in spectroscopy and HPLC.
Features
- 65pC saturation capacity for wide dynamic range
- Wide spectral response (180 – 1000nm) for UV and IR response
- NP junction photodiodes with superior resistance to UV damage
- Low dark current
- Integration time up to nine seconds at room temperature
- Integration time extended to hours by cooling
- High linearity
- Low power dissipation (less than 1mW)
- Geometrical structure for enhanced stability and registration
- Standard 22 lead dual-in-line IC package

Si photodiode arrays consist of multiple photodiode elements, formed in a linear or matrix arrangement in one package. Some arrays are supplied coupled with a CMOS multiplexer. The multiplexer simplifies design and reduces the cost of the output electronic circuit. Our Si photodiode arrays are used in a wide range of applications such as laser beam position detection, color measurement and spectrophotometry.

Detection Technology provides both standard and customized single-row and multi-row photodiode arrays.
The standard ARB photodiode array series is available with 1.5 mm, 1.6mm and 2.5 mm pixel pitches. All the arrays are available both without scintillators or with a scintillator selected from a wide range of alternatives selected based on the required energy levels and performance.
The photodiode geometry can be customized to literally any shape and dimension. Based on the requirements on the characteristics and application environment given by customers, Detection Technology's application specialist team selects from its wide-range photodiode technologies, processing technologies as well as other design parameters to build a tailored solution.
