A complete set of all known publications produced by The Museum of Primitive Art from its founding in 1957 to its closing in 1974.

Seventy exhibition catalogs published between 1920 and 1936, when the Kraushaar Gallery was located at 680 Fifth Avenue in New York City.

Titles that reflect the subject matter and wide geographical breadth of Goldwater Library's collection and the curatorial department it serves, The Michael C. Rockefeller Wing.

Rare monographs, auction catalogs, museum collection catalogs and archaeological treatises on Egyptian and classical antiquities.

Primarily from nineteenth- and early-twentieth century Russia or the Ukraine, this collection includes a wide array of themes and formats.

Over 450 exhibition checklists and pamphlets from 1895-1953, held by the Thomas J. Watson Library and the Frick Art Reference Library.

Gifts from J. Pierpont Morgan, Samuel Putnam Avery, and other founders and early trustees of the Museum established the foundation of the Libraries' rare book collections. Generous donors provide funding for the continuing growth of this already strong collection of treatises on art and architecture, early travel books, archaeological studies, rare collection catalogs, early trade catalogs, artists’ manuals and handbooks, complete runs of seminal journals, fencing books, scrapbooks, fine bindings, and examples of fine printing.

This collection contains rare, valuable, and important works held in the Thomas J. Watson Library and other curatorial department libraries at The Metropolitan Museum of Art.

Thorlabs' LED Ring Light Source consists of 40 individual broadband, daylight white LEDs in a ring-shaped array with a Ø0.99" (Ø25.1 mm) clear aperture. By angling the LEDs, this ring light illuminates areas from 50 mm to 300 mm along the emission axis that can then be viewed through the clear aperture, making it ideal for machine vision applications.

For convenient connection to the drivers listed below and on the LED Drivers tab, the LED ring light has a connection cable with an M8 connector; see the Pin Diagram tab for the M8 connector pin information. This LED ring light also features an EEPROM chip which stores information about the LED (e.g., current limit, forward voltage). When controlled by a Thorlabs UPLED, DC40, or DC2200 LED driver, this data can be used to implement smart safety features.

Thorlabs also offers a range of unmounted, mounted, collimated, and fiber-coupled LEDs that are designed for a variety of applications, including microscopy, illumination, and measurements. For questions on choosing an appropriate LED and to discuss mounting requirements, please contact Tech Support.

White Light LEDsThis illuminator is a daylight white LED ring featuring a broad spectrum that spans several hundred nanometers; see the table to the right for a typical output spectrum. It has a correlated color temperature 5500 K, which indicates that the color appearance is similar to a black body radiator at the same temperature. In general, warm white LEDs offer a spectrum similar to a tungsten source, while cold white LEDs have a stronger blue component to the spectrum; daylight white LEDs provide a more even illumination spectrum over the visible range than warm white or cold white LEDs. To discuss LED ring lights with other correlated color temperatures or nominal wavelengths, please contact Tech Support.

To fully support the max optical power of the LED you intend to drive, ensure that the max voltage and max current of the driver are equal to or greater than those of the LED.

The diagram to the right shows the male connector of the LEDRW40 Ring Light. It is a standard M8 x 1 sensor circular connector. Pins 1 and 2 are the connection to the LED. Pin 3 and 4 are used for the internal EEPROM. If using an LED driver that was not purchased from Thorlabs, be careful that the appropriate connections are made to Pin 1 and Pin 2 and that you do not attempt to drive the LED through the EEPROM pins.

Driver OptionsThorlabs offers four drivers compatible with this LED ring light: LEDD1B, DC40, UPLED, and DC2200. See the LED Drivers tab for compatibility information and a list of specifications. The UPLED, DC40, and DC2200 drivers are capable of reading the current limit from the EEPROM chip of the connected LED ring light and automatically adjusting the maximum current setting to protect the LEDs. The DC40 LED driver can provide drive currents with up to a 5 kHz modulation when supplied with an external modulation signal. While the DC2200 driver is capable of modulating frequencies up to 250 kHz, the LED ring light must not be modulated at or above 9 kHz.

Constructed from anodized aluminum, this LED ring light housing features four 4-40 tapped holes that are compatible with our Ø6 mm ER cage rods, allowing for integration with 30 mm cage systems. The housing also features three setscrews on the sides for interfacing with various camera lenses and high-magnification zoom lens systems (as seen in the photo in the bottom right), which can be secured using a 5/64" (2.0 mm) hex key or balldriver. An M60 x 1.0 external thread at the head of the ring light gives the option of attaching various elements such as custom filters or diffusers.
