The mechanical dimensions of an optical power sensor can be quite relevant for applications, e.g. when a sensor needs to be temporarily inserted into some beam path, where there is little available space. There are some very flat hand-held sensors, mostly based on photodiodes, which require quite little space. Thermal power sensors are intrinsically relatively slow – particularly those for high powers, where the thermal capacity of the sensor is tentatively higher. Typical response times are of the order of 0.2 s to 2 s. Even photodiode-based power meters are normally not made very fast, since one could anyway not read a display which is updated e.g. 10. Power meters require some electrical power, which may either be provided with an external power supply or with batteries (which are normally rechargeable). Battery-powered operation is of course convenient by eliminating another cable enter the requirement of a nearby power socket, but on the other hand the need for regular recharging can also be i.
