Applications
Micros is suited for applications that involve microscopic temperature distributions. Below are a few examples:
Electronics
Detect heat flow and temperature distributions on electronic devices, like SMD components and semiconductor devices.
Optical Devices
View the thermal gradients on displays and laser diodes on a microscopic level.
Materials
Identify thermal flow within laminar.
MEMS
Analyze the thermal performance of micro-electromechanical systems.
Medical
Examine the thermal response to medical treatments.
Chemical Reactions
Study microscopic events of exothermic and endothermic reactions.

Image Quality
Pixel resolution refers to the size of the target area that the lens attempts to focus onto an individual detector pixel. Lens performance, however, describes how precisely that target area is focused on the pixel. Spatial resolution represents the size of the smallest distinguishable feature. When a lens is designed properly, the lens's spatial resolution equals the pixel resolution. A poorly designed lens will result in image blur, diminishing spatial resolution. The figures below demonstrate the effect lens performance can have on spatial resolution. Both lenses have a pixel resolution of 5µm. The spatial resolution of the properly designed lens (below left) matches the pixel resolution. The spatial resolution of the poorly designed lens (below right) cannot achieve the pixel resolution.
Properly Designed Lens (LW320-12 5µm Lens)
5µm lines can be perceived on the Group 6 Element 5 (4.92µm, see table below).
Poorly Designed 5µm Lens
The smallest perceivable lines are Group 6 Element 1 (7.81µm).
