Replace the current light source of your enlarger with a long-term stable modern LED panel light. Individual adaptation is supplied by Heiland electronic.
Using LEDs with the primary colors red, green, and blue allows controlling white light for focusing, as well as controlling any color separately. Even mixed light consisting of green and blue is possible. The luminous colors are adjusted for multigrade paper and deviate at most +/-2 nanometers from the specified wavelength.
Precise switching on and off is easily possible even without a shutter. Gradation and intensity can be adjusted reproducibly.

This option enables to select one of 4 colors – red, green, blue or white – for film or transmission measurement. This may be very helpful in one of the most common tasks while measuring the density of stained films, e.g. developed by Pyrogallol, Finol or Tanol.
The mentioned option enables to measure the visual density by using white or green light as well as the stain density by switching to blue light.

Further on that option might be very helpful in technical and biometrical applications where the density measurement in a dominant wavelength range is required..

LED darkroom light

•  
• LEDs guarantee immediate switching on and off, and a long term stable light output.
•  
• No need for lamp replacement.
•  
• Secure and bright red light at 630nm wavelength.
•  
• White light with approximately 5000k enables fast checking of already fixed prints.
•  
• Adjustable intensity according to your application needs.
•  
• A 12V DC power supply ensures electrical safe work even in wet room

Control of the LED cold light source via time switch or analyser

If you already have a timer, it can be used for controlling the lED light source

A small control unit with rotary knobs and a red LCD

display connects your timer with the 24V power supply

unit and the LED cold light head.

Pre-selection of the operating mode with light colour

paper grade, and intensity is done reproducibly at

the control unit.

This unique system facilitates and accelerates the making of high-quality black-and-white photographs on multigrade paper. First of all, by measuring areas of light and shadow of the projected negative, the user determines contrast and brightness on the easel. For over 30 default paper calibrations, a first suggestion for the right exposure will immediately be calculated with 1/10 f-stop / gradation level accuracy. Via the unique filter control with shutter function, these measurements will automatically be transformed into a split exposure. Furthermore, there is no limit to any possible manual corrections and post-exposure. Image results are developed much faster and creative working is encouraged, instead of limited.

Convenient control of exposure time, grade and burn in time functions through the usage of rotary knobs with rest stops and large red LED displays.
By pressing the rotary knob, either you switch on the focus light or start the exposure time.
Using the implemented LED segments of a zone scale, you pre-visualise the approximate tone value of any area inside the final print in reference to the brightest and darkest areas. This feature enables the placement of tone values even in prints without highlights or shadows. A really helpful tool in printing high-key or low-key negatives

SPLITGRADE® COMFORT is connected to the existing controller via the COM1 port and is equipped with a socket for the foot switch. So you may place the COMFORT unit in front of your working place, controlling daily work with it. For all other functions like changing the paper or film setting use the controller as usual.

The Heiland TAS film processor is a novel and unique addition to the home, college or club photo lab: an automatic 35 mm and 120 mm roll film tank agitation system.

• reproducible results
• ends monotonous manual agitation
• small size – fits in every darkroom
• transportable – could also be used in campers and cars (12v or 24v supply)
• easy handling
• ideally suited for Zone System and for two bath processes
• uses existing tanks for 35 mm and 120/220 films
• ideal for photography clubs with exchangeable modules for every user
• variable speed settings
• automatically compensates total development time depending on programmed temperature
• solid construction, long life metal case; reliable quality from Heiland electronic – Made in Germany

As a photography enthusiast you probably prefer to develop films in your own darkroom. However, development by hand is a time consuming, even boring procedure especially if one has a stack of films to develop after a holiday or photo-assignment. Nevertheless, consistent results based on a tested combination of film types, exposure and development are of prime importance.

To this end Heiland Electronic GmbH has produced the TAS processor. It will satisfy the most discerning of darkroom devotees, in particular 'Zone System' specialists. Moreover, it is compatible with Paterson, JOBO, Kaiser and Kindermann development tanks and can be adapted to suit other makers of tanks.

Operation is extremely simple

• Enter the development parameters
• Load tank with film(s) (standard procedure in total darkness!)
• Fill tank (tap on table to release bubbles) keeping it vertical
• Attach tank to holder and fasten clamp
• Press start button

The TAS starts with a continuous agitation, followed by intervals of pauses and agitation. The process end is signalled by beeps at 30, 20 and 10 seconds before and after the process stops.

Due to the flexible programming you could use the TAS for fixing and washing as well.

Thanks to its low cost interchangeable 'memory stick' system several users can benefit from one machine, allowing them to program individual combinations of developer / time e.g. N-1, N+1.

For a tilt only operation, a single turn of a knob suffices – even while the processor is running.

Automatic processing with the TAS allows you to continue with other work such as loading another tank, preparing more chemicals or completing finishing steps, e.g. fixing, washing, drying and archiving the negatives.

Simplicity of design and engineering, plus the use of high quality materials guarantees an effective and long life for the HEILAND TAS film processor. It has been developed in partnership with B-DESIGNS, initiated to meet the requirements of practical photographers. Please don't hesitate to contact us if you need a special version or want to use special tanks.

Densitometer

By means of precise measurement of the optical density, the exposure and development of film and paper can quickly be optimized.

Additionally, the monitoring of technical processes of transparent materials is very easy since thickness and optical density correlate. Measurements up to 6 logD (<1/1000000 transmittance) can be reliably determined with special models of our devices.

Devices by Heiland electronic usually work monochromatically within the visual spectrum and can be individually adjusted according to their task.

Type TRD 2

This device enables density measurement of films and papers and its basic version is already suitable for all typical measurements in black-and-white photography. The following options can be ordered additionally:

• Exchangeable apertures
