16mm High Speed Camera

 

 

Return

The new Hycam IIA family of 16mm high-speed rotating prism film cameras incorporates design changes that significantly improve camera performance.  A key electronic design change incorporated new speed control and shutter-pulse sensors in the camera’s optical head.  The camera’s improved servo brake design combined with electronic upgrades, significantly enhance top-end performance at speeds above 8,000 fps (frames-per-second).  In addition, there is much less end-of-film shatter at the end-of-the-run.

These improvements are also available as upgrades to existing Hycam I and Hycam II cameras.
 

Hycam IIA Features include:
. Full-frame speeds of 100 to 12,000 fps, 200 to 24,000 fps with ½ frame optical head and 400 to 48,000 fps with the ¼ frame optical head.
. Flat-film or image plane with frame lines.
. Input power, choice of: 115VAC 60Hz, 230/240VAC 50Hz or 120volts DC.
. Accurate electronic servo control over the camera’s entire speed range.
. Accepts standard "C" mount lenses.
. Interchangeable shutters with ratios of: 1:2.5 to 1:100 provides shutter speeds of one microsecond or less.
. Built-in crystal controller Timing Pulse Generator with selectable frequencies of: 100, 1000 and 5000 Hz, includes dual LED timing lights.
. Event synchronizer with isolated output contacts; Closure, and /or Open.
. Optional 15-volt square wave output shutter pulse signal, for strobe or laser synchronization.
. Optional HDRS numeric TIME annotation of 12 digital characters on each film frame and at all camera speeds without optical or electronic parallax. Time resolution to .00001 seconds on each film frame.

A new upgrade is now available that greatly enhances the operation of early model 16mm Hycam I and Hycam II high-speed cameras.  It's both electronic and mechanical.  The result is the NEW Hycam IIA performance at a very modest cost.

New electronic technology provides a level of reliability at speeds above 8,000 fps that was not possible with earlier designs.  For example, speeds are now truly regulated at ±1% at top speeds with MORE TIME at selected speeds.  In addition, end-of-film shatter, common with all high-speed rotating prism cameras, is now virtually eliminated.

A complete mechanical refurbishment is included in the process.  The latest mechanical components along with new replacement parts such as; bearings, rollers, guides, brake bands, LED timing lights etc, are included.

Users can now switch-select film capacity of 400' or 450'.  This assures a maximum amount of film oat the selected top speeds by optimizing drive limiter circuits while minimizing end-of-film shatter.

Before
Description

A new generation IR speed sensor is installed in the camera's optical head.  This sensor produces a clean and undistorted 0 -15-volt reference pulse at all camera speeds.  It's used as a feed back signal to the speed control electronics to assure that the cameras is running at the selected speed.

Early generation Hycam II's used mid 1970's era  sensors that performed correctly to about 6,000 frames-per-second.  At higher camera speeds, the signal produced was distorted and unreliable.  This poor signal caused the speed control electronics to respond erratically and frequently resulted in runaway or non-servo controlled top speeds.  Most users accepted the mass of end-of-film chips without knowing the camera was in a run-away mode.  the Hycam IIA upgrade has corrected this long-standing design deficiency.

In addition , each camera receives a complete mechanical overhaul,  The latest production design improvements are included with new replacement parts as necessary.  The motor is disassembled, commutator cleaned with brushes and bearings replaced when needed.  This includes re-packing the motor's viscous clutch.  The motor is then tested for correct performance.  This upgrade makes your older Hycams run like new cameras.
