For TIRF Imaging ― Make Your World Flat

If you are imaging in Total Internal Reflection Fluorescence (TIRF) mode, your world must be very flat. Even very slight curvature or flexing of the surface of a dichroic used to reflect a TIRF laser results in astigmatism. This distorts the reflected laser beam ― and that results in a less-than-optimal evanescent wave for your … Continue reading

Flat Optics: Flattening the Curve

Many of today’s systems from smartphones to LiDAR systems in autonomous vehicles contain optical elements. The continued trend towards technology miniaturization poses a challenge to the field of optics because classical lenses and mirrors tend to be bulky. One way of dealing with this challenge is the increased use of flat optics. Over the past … Continue reading
