Optimal camera selection with minimal effort
Hamamatsu Photonics develops cameras utilizing image sensor technologies such as sCMOS and TDI sensors. In addition, through more than 100 optical measurement simulations conducted annually, we have accumulated extensive expertise in optical measurement. Leveraging this experience and knowledge, we also apply our proprietary simulation engine to OEM camera development, enabling efficient selection of cameras optimized for specific customer applications.
Selecting the most suitable image sensor technology is a key step in OEM camera development. For example, when imaging large-area objects, it is important to evaluate whether a tiling approach using two-dimensional sensors such as sCMOS, or a line-scan approach using a TDI sensor, will deliver better sensitivity and throughput under the customer’s actual operating conditions. However, these evaluations typically require significant time and cost to build test environments, and when multiple candidate approaches are available, there is a risk that prototype development may also proceed before the optimal imaging method has been definitively identified. Using our simulation engine, sensitivity and throughput can be modeled for scenarios in which a customer’s target object is imaged with different sensor technologies, as shown in Figure 1. This reduces development time and cost while supporting informed selection of the most appropriate image sensor technology.

Furthermore, even within the same image sensor technology, differences in characteristics such as quantum efficiency, pixel size, readout noise, and readout speed make the selection of an optimal sensor a time- and effort-intensive process. Our simulation engine supports comparisons within the same technology, contributing to the efficient narrowing down of image sensors best suited to specific customer applications. For example, in applications where sensitivity is a critical factor, the sensitivity performance of different image sensor technologies can be compared, as shown in Figure 2. In addition, if customers are already using third-party cameras, those cameras can be set as target specifications and included in comparative evaluations. For further details, please contact us.

Experience a simple simulator on the web
Our Camera Simulation Lab* lets you try a simple web-based simulator. This tool allows you to view simulated images by selecting the sample type and imaging conditions.
* This tool differs from the actual simulation engine used in OEM camera development.
Thermal simulation available from early camera design stage
Based on customer requirements, we carry out camera enclosure design and thermal simulations of cooling mechanisms from the early stages of camera development. After assessing the customer’s operating environment and requirements, we incorporate analysis results, such as temperature distribution and thermal fluid behavior, into the mechanical design to optimize performance, cost, and camera size from the outset of OEM camera development.
