DALS

Unique Features

Under Collaborative mode, the grader can get an expert opinion on the grade from senior graders located elsewhere
Under Collaborative mode, the factory can get approval from the sales team for any anomalies
Under remote session, helps build consumer confidence by showing the diamond online to the buyer in real-time, under the microscope
Reduces grading time considerably, as inclusions can be quickly noticed
Measures the size of inclusion to add objectivity to diamond grading
Measure the size of a facet or the edge between two facets
Direct measurement of table size in micrometres (the only tool other than HeliumPolish-CrownReflect)
Measure angle between two edges
Measures depth of inclusion from adjacent features
High Optical and Digital zoom without compromising image quality, helping the grader considerably
Fatigue-free operation for the grader, increasing his output
Helps in educating and training new graders quickly. Possible to train graders remotely as well
Produces stacked images for documentation and future reference by creating the library
Create a communication tool between the grader and the polisher, without anyone leaving their place. Will reduce repeated instructions and repairs (include the chart of the available symbols)
Auto Contrast and Image stabilization for crystal clear image on the screen
The following Lighting modes are available:
- Continuous Dark Field (real-time streaming for online customers)
- Continuous Top Light
- Continuous Reflective light (for surface features)
- Adaptive Light for glare-free viewing (grading and within-team communication)
- Normal Map (for texture mapping)
- Photometric Stereo (for producing inspection images for challenging surfaces, including highly reflective objects or surfaces with significant 3D characteristics)
- Albedo (for producing a direct light image)
Possibility to shoot video (as well as the screen) with Audio in:
- High Quality
- YouTube Quality (can be uploaded to YouTube instantly)
- WhatsApp Quality
The new ergonomic design
The combination of a conical and parabolic reflector guarantees an optimal, highly efficient dark-field lighting, perfect for examining even the smallest inclusions without blinding or confusing the user
Revolutionary overhead Adaptive-Light illumination combined with DarkField light offers REFLECTION-FREE illumination to empower human observation and enhance machine vision
The long working distance and narrow objective body design allow easy manipulation of the diamond during the inspection

DALS can be very helpful in the following situations:

Teams from different manufacturing locations can share the microscope image of the rough, semi-polish, or polish diamonds in real-time, and can debate over different ideas. Use audio from the DALS software to create a relation between the image on the screen and the dialogue.
The manufacturing department can discuss the stone with the head of manufacturing or the sales team without sending the diamond across physically. An instant decision can be achieved with full consensus.
Polish diamond evaluation and pricing can be completed remotely by the sales team. Cutwise can additionally help here.
Create a library of Digital Clarity Masters (all departments located in different countries can use the same clarity master for consistency in grading)
Shoot videos of specific features and share them with the team or online buyers
Communication between the grading department and the polishers (to help correct the right facet and avoid errors). This reduces the conflict considerably.
Create an education program for training graders.
