Used JEOL JWS 7515 #9412229 for sale

JEOL JWS 7515 is a scanning electron microscope (SEM) that combines high resolution with excellent depth of field. Its design is based on the proven JEOL JMS series of SEMs that feature a fine stage sample flatness of better than 1.7mm. JEOL JWS-7515 maximizes resolution and image contrast by using a cold field emission gun (FEG) and a digital image detector. It offers high speed imaging with a live frame rate of up to 200 frames per second. JWS 7515 is a mid-high vacuum SEM, meaning it operates at a pressure range of medium secondary to high primary vacuum. In this type of environment, electrons can travel easily and with few collisions. This creates a high resolution image with good depth of field, as electrons emitted from the FEG are accelerated through the objective lens and towards the sample on the stage. The objective lens of JWS-7515 can be adjusted to get clear images over a range of magnifications from 5x to 300kx. JEOL JWS 7515 includes a gas purging equipment and automated stage controls. This allows the user to adjust the position of the sample and precisely locate elements of interest. The vacuum conditions can be maintained even during manual operation of the stage through the gas purging system. The gas purging unit also prevents contaminants from entering the vacuum space of the SEM. JEOL JWS-7515 has several features to enhance imaging in the SEM. These include contrast and color digital imaging, Beam Current Monitor (BCM), and Automated Backside Imaging (ABi). The contrast and color digital imaging mode improves the clarity and contrast of low signal samples, while BCM helps maintain consistent imaging conditions. Through ABi, users can image and measure features on the reverse side of a sample, as well as analyse shapes and surface morphology on both sides. JWS 7515 is an excellent choice for many SEM applications thanks to its high resolution and depth of field. It has a range of features and utilities to improve imaging quality and accuracy. Its gas purging machine and automated stage controls make it ideal for demanding applications. With its high speed frame rate, JWS-7515 can take detailed images fast.
