Animal care depends on good science, and good science is produced by data driven by proper measurements. Light quality needs to be measured to ensure proper animal care, just like other environmental factors such as water quality and airflow.

LIGHT MEASUREMENT KITS

ZLI is an official reseller of scientific instruments which are necessary to measure light quality adequately. StellarNet Spectrometers, Solar PathFinders and Sky Quality Meters can help you build a data set for the future, to aid you in perpetual husbandry improvements. As a Nonprofit Reseller, a portion of every purchase goes directly to research scholarships designed to improve wildlife conservation and animal welfare initiatives.

ZLI TS (TERRESTRIAL SPECTROMETER) KIT

Available to Donors for $5000 or greater
The ZLI Terrestrial Spectrometer Kit, enables the measurement of light quality and quantity in an animal exhibit and holding area. It also enables analysis of animal coloration, an important indicator of health and well-being.
We use StellaNet UV-VIS Spectrometers capable of recording light wavelengths from 190-850nm. This enables animal keepers and researchers to measure the light animals are sensitive too, and to move beyond guess-work in animal care to a solid scientific foundation for more sensitive animal welfare decisions. The included Spectro-Wiz software is easy to use and flexible for a variety luminous habitat assessments, including critical assessments of light quality and intensity over the course of time (day and seasonal variations).

 

ZLI QQS (QUALITY, QUANTITY, STRUCTURE) KIT

Available to Donors for $6000 or greater
The ZLI QQS Kit, enables the measurement of light quality, quantity and structure in an animal exhibit and holding area. In addition to quality and quantity, it enables analysis of the structure of radiance impacting an animal’s space.

The ZLI QQS Kit includes the terrestrial spectrometer kit, a solar pathfinder and associated software, as well as an SQM meter to determine the qualities of natural light in the exhibit area. These devices are eminently portable, allowing for comparison between the qualities of an animal’s indigenous habitat along with those of the managed care space.

 

ZLI QQS+HA (HEALTH ASSESSMENT) KIT

Available to Donors for $10000 or greater
The ZLI QQS with Health Assessment, adds the ability to measure animal coloration along with the many uses the ZLI TS Kit can be put to. This is important to sensory ecology concerns, as well as to the ways in which groups of animals function together and within their environment.

The ZLI TS+HA Kit adds the ability to measure material reflectance to the ZLI QQS Kit, by adding a tungsten Halogen light source and appropriate reflectance and probe accessories. An indispensable tool to measure vital color changes to feathers, skin, exhibit surfaces and the like.

ZLI NIGHT VISION SELECTION

ZLI Bushnell Binoculars
Suitable for both night and day vision, the 4×50 Equinox Z Digital Night Vision Bi-ocular from Bushnell features a digital night vision sensor that is completely resistant to bright light and has an unlimited lifetime. The right objective aperture is dedicated to provide a single optical path for a bi-ocular viewing, while the left objective aperture houses a built-in infrared illuminator. The optics offer a notable 4x magnification that will keep image jitter low when you use this NVD as a handheld device. The 50mm objective allows your bi-ocular device to collect more light than an average device, which will further increase the brightness of your images and videos. If the ambient infrared from the moon and the stars doesn’t provide enough illumination, you can use a built-in infrared light to ensure your target’s visibility. With a variable output power, the infrared light source should add sufficient brightens to your targets. To offer versatility, the bi-ocular also has adjustable digital coarse focus and a video output.

 

ZLI PORTABLE NIGHT PHOTOGRAPHY

ZLI DSLR Sony A7s II
The a7S II Mirrorless Digital Camera from Sony offers an impressive blend of sensitivity, dynamic range, resolution, and speed to benefit a versatile multimedia workflow. Revolving around a full-frame 12.2MP Exmor CMOS sensor, the a7S II is capable of internal UHD 4K recording at 30 fps with full pixel readout as well as 1080p recording at up to 120 fps, all in the XAVC S format. For both stills and video recording, the BIONZ X image processor also pairs with the sensor to enable expanded sensitivity to ISO 409600, continuous shooting to 5 fps, and fast intelligent autofocus with low-light sensitivity to -4 EV.

 

ZLI PROFESSIONAL NIGHT VIDEO KIT

Canon ME20F-SH Cinema Package
Canon has taken their powerful yet small ME20F-SH and combined it with a variety of accessories to create the ME20F-SH Cinema Package. The camera and included items make for a flexible and tantalizing camera package. Included in the accessories are a Zacuto Mini Baseplate, Atomos Shogun Flame, 240GB SanDisk SSD, Delvcam articulating arm, IDX Endura V-Mount battery system, HDMI cable, and 4-Pin XLR power cable. The camera itself is only a little bit larger than the full-frame sensor it houses, yet it captures Full HD with a rated ISO of over 4 million. It will capture up to 60p and features a locking Canon Cinema EF mount.
