KODA Technical Pani Film 2415 helps yourecor the stun and nearly evyhing une it.

* What do you call a film you can usefor solar flare photography, photomi-

-orography, line-scan recording withcathode-ray tubes, lasers, or hght-enitting diodes, photographing holo-graphic reconstructions, and aIso for

;making black-and-white slides?We call it KODAK Technical Pan Film2415. You mitht call it "a film for allfical lengths, because it has beenused rewardingly to record imagerywith. high-power microscope objec-

--tives, asroomcl telescopes, and allsorts ofcamera lenses in between.T extraordary fm, previouslyintroduced as SO-115, is intended for

a wide range of applications requiringhigh resolution, extremely fine gram,processing flexibility, high D-max,and relatively flat spectral responsethrough most of the visible spectrum.It is coated on EsTAR-AH Base.Its unusual combination of perform-ance characteristics allows TechnicalPan Film to fill a void in the matrixofblack-and-white photorecordingfilms. These characteristics havemade 2415 a worthy successor toKODAK Solar Flare Patrol Film(EsTAR-AH Base) SO-392 and KODAKPhotoicr aphy MonochromeFilm SO4Irand a valuable alter-

native to KODAK High Contrast CopyFilm 5069 in most applications.You won't find a Kodak film with abroader range of scientific and tech-nical applications. At the same time,you may wish to load a roll into your35 mm camera to record some stun-ning pictorial photography.For additional information on Tech-nical Pan Film, write to EastmanKodak Company, Deartment 412L-153, Rochester NY 1450.

MOP +YOU:instant image analysis.For a multitudeof geometric dimensions

The new MOP quantitative systemfor morphological and stereo-logical image analysis is unique:Only MOP lets the operator's dis-criminating judgment interact withthe high-speed calculation abilityand memory of a microcomputerThis mode of operation is highlyreliable in applications wherefully automatic systems fail.

Single key selectsa multitude of functions

MOP is portable, requires no in-stallation and practically no oper-ator training. Yet it can measure 8parameters simultaneously, storedata in 20 channels, and per-form statistical analyses such asdistribution histograms. Easilyinterfaced to computers for data-banking and high-level statistics.Nationwide service.
