In today's stadium theatres the focus is on high-quality cinema images and large screens. This requires a new measurement tool to evaluate and compare lens system performance. The new Schneider Test Film CLT 2000 is such a tool. This Test Film is the only one designed specifically for lens performance evaluation, in addition to the other standard functions such as format verification and projector steadiness testing.
This Test Film was deliberately designed to be a very tough test for cinema lenses. Schneider Cinema lenses have nothing to fear from this Test Film, but even Schneider lenses need their performance verified at regular intervals. Here are a few of the many unique features of this film:
+MTF test patterns (up to 100 LP/mm) are located at areas that are critical for anamorphic evaluation, as well as for flat lenses.
+The horizontal and vertical grid allow evaluation of lens distortion as well as keystoning and curved screen geometric distortion.
+The high contrast black background reveals excess projector heat problems. It also shows lens chromatic aberration clearly.
+All common formats are shown, with their inch and metric units readily visible, for filing plates.
+The high contrast of this Test Film is ideal for evaluating lens flare and veiling glare.
+Format dimensions correspond to SMPTE recommended practices and standards.
